Daya Bay

An international collaboration of physicists working on a neutrino experiment in southern China announced today they have made a difficult measurement scientists have been chasing for more than a decade.

The results of the Daya Bay neutrino experiment open an important window into understanding the behavior of neutrinos, and now the race is on to determine the implications. Two American experiments, one proposed and one under construction, seem well positioned to take the next steps.

    Proton Collision ->Decay to Muons and Muon Neutrinos ->Tau Neutrino ->

    .....tau lepton may travel some tens of microns before decaying back into neutrino and charged tracks




     Before I comment on the result, let me give you a little background on the whole thing. Opera is a very innovative concept in neutrino detection. Its aim is to detect tau neutrino appearance in a beam of muon neutrinos. A Six-Sigma Signal Of Superluminal Neutrinos From Opera!

    The OPERA result is based on the observation of over 15000 neutrino events measured at Gran Sasso, and appears to indicate that the neutrinos travel at a velocity 20 parts per million above the speed of light, nature’s cosmic speed limit. Given the potential far-reaching consequences of such a result, independent measurements are needed before the effect can either be refuted or firmly established. This is why the OPERA collaboration has decided to open the result to broader scrutiny. The collaboration’s result is available on the preprint server arxiv.orghttp://arxiv.org/abs/1109.4897.

    In order to perform this study, the OPERA Collaboration teamed up with experts in metrology from CERN and other institutions to perform a series of high precision measurements of the distance between the source and the detector, and of the neutrinos’ time of flight. The distance between the origin of the neutrino beam and OPERA was measured with an uncertainty of 20 cm over the 730 km travel path. The neutrinos’ time of flight was determined with an accuracy of less than 10 nanoseconds by using sophisticated instruments including advanced GPS systems and atomic clocks. The time response of all elements of the CNGS beam line and of the OPERA detector has also been measured with great precision.

    By classifying the neutrino interactions according to the type of neutrino involved (electron-neutrino or muon-neutrino) and counting their relative numbers as a function of the distance from their creation point, we conclude that the muon-neutrinos are "oscillating."

    We present an analysis of atmospheric neutrino data from a 33.0 kiloton-year (535-day)exposure of the Super-Kamiokande detector. The data exhibit a zenith angle dependent de ficit of muon neutrinos which is inconsistent with expectations based on calculations of the atmospheric neutrino flux. Experimental biases and uncertainties in the prediction of neutrino fluxes and cross sections are unable to explain our observation. . Evidence for oscillation of atmospheric neutrinos

    Cherenkov radiation


    Taking the formalisms of electromagnetic radiation and supposing a tachyon had an electric charge—as there is no reason to suppose a priori that tachyons must be either neutral or charged—then a charged tachyon must lose energy as Cherenkov radiation[15]—just as ordinary charged particles do when they exceed the local speed of light in a medium. A charged tachyon traveling in a vacuum therefore undergoes a constant proper time acceleration and, by necessity, its worldline forms a hyperbola in space-time. However, as we have seen, reducing a tachyon's energy increases its speed, so that the single hyperbola formed is of two oppositely charged tachyons with opposite momenta (same magnitude, opposite sign) which annihilate each other when they simultaneously reach infinite speed at the same place in space. (At infinite speed the two tachyons have no energy each and finite momentum of opposite direction, so no conservation laws are violated in their mutual annihilation. The time of annihilation is frame dependent.) Even an electrically neutral tachyon would be expected to lose energy via gravitational Cherenkov radiation, because it has a gravitational mass, and therefore increase in speed as it travels, as described above. See: Tachyon
     ***
    An early set of experiments with a facility called the solar neutrino telescope, measured the rate of neutrino emission from the sun at only one third of the expected flux. Often referred to as the Solar Neutrino Problem, this deficiency of neutrinos has been difficult to explain. Recent results from the Sudbury Neutrino Observatory suggest that a fraction of the electron neutrinos produced by the sun are transformed into muon neutrinos on the way to the earth. The observations at Sudbury are consistent with the solar models of neutrino flux assuming that this "neutrino oscillation" is responsible for observation of neutrinos other than electron neutrinos. See: Detection of Neutrinos

    P.I. Chats: Faster-than-light neutrinos?

    Measurements by GPS confirm that the neutrinos identified by the Super-Kamiokande detector were indeed produced on the east coast of Japan. The physicists therefore estimate that the results obtained point to a 99.3% probability that electron neutrino appearance was detected.Neutrino Oscillations Caught in the Act

    Using the NuMI beam to search for electron neutrino appearance.

    The NOνA Experiment (Fermilab E929) will construct a detector optimized for electron neutrino detection in the existing NuMI neutrino beam. The primary goal of the experiment is to search for evidence of muon to electron neutrino oscillations. This oscillation, if it occurs, holds the key to many of the unanswered questions in neutrino oscillation physics. In addition to providing a measurement of the last unknown mixing angle, θ13, this oscillation channel opens the possibility of seeing matter/anti-matter asymmetries in neutrinos and determination of the ordering of the neutrino mass states.See:The NOνA Experiment at Fermilab (E929)

    Linking Experiments

    Illustration: Sandbox Studio

     

    The first round of physics

    Nine proposals are under consideration for the initial suite of physics experiments at DUSEL, and scientists have received $21 million in NSF funding to refine them. The proposals cover four areas of research:
    • What is the nature of dark matter? (Proposals for LZ3, COUPP, GEODM, and MAX)
    • Are neutrinos their own antiparticles? (Majorana, EXO)
    • How do stars create the heavy elements? (DIANA)
    • What role did neutrinos play in the evolution of the universe? (LBNE)
    In addition, scientists propose to build a generic underground facility (FAARM) that will monitor the mine's naturally occurring radioactivity, which can interfere with the search for dark matter. The facility also would measure particle emissions from various materials, and help develop and refine technologies for future underground physics experiments.
    But why are there four separate proposals for how to search for dark matter? Not knowing the nature of dark-matter particles and their interactions with ordinary matter, scientists would like to use a variety of detector materials to look for the particles and study their interactions with atoms of different sizes. The use of different technologies would also provide an independent cross check of the experimental results.
    "We strongly feel we need two or more experiments," says Bernard Sadoulet of UC Berkeley, an expert on dark-matter searches. "If money were not an issue, you would build at least three experiments."
    The largest experiment intended for DUSEL is the Long-Baseline Neutrino Experiment (see graphic), a project that involves both the DOE and NSF. Scientists would use the LBNE to explore whether neutrinos break one of the most fundamental laws of physics: the symmetry between matter and antimatter. In 1980, James Cronin and Val Fitch received the Nobel Prize for the observation that quarks can violate this symmetry. But the effect is too small to explain the dominance of matter over antimatter in our universe. Neutrinos might be the answer.
    The LBNE scientists would generate a high-intensity neutrino beam at DOE's Fermi National Accelerator Laboratory, 800 miles east of Homestake, and aim it straight through the Earth at two or more enormous neutrino detectors in the DUSEL mine, each containing the equivalent of 100,000 tons of water.
    Studies have shown that the rock at the 4850-foot level of the mine would support the safe construction of these caverns. In January, the LBNE experiment received first-stage approval, also known as Mission Need, from the DOE.
    Lesko and his team now are combining all engineering studies and science proposals into an overall proposal for review.
    "By the end of this summer, we hope to complete a preliminary design of the DUSEL facility and then integrate it with a generic suite of experiments," Lesko says. "While formal selection of the experiments will not have been made by that time, we know enough about them now that we can move forward with the preliminary design. The experiments themselves will be selected through a peer-review process, as is common in the NSF."
    If all goes well, Lesko says, scientists and engineers could break ground on the major DUSEL excavations in 2013, marking the start of a new era for deep underground research in the United States. SEE:Big Plans for Deep Science

    Neutrinoless Double Beta Decay

    You don’t see what you’re seeing until you see it,” Dr. Thurston said, “but when you do see it, it lets you see many other things.Elusive Proof, Elusive Prover: A New Mathematical Mystery


    The Enriched Xenon Observatory is an experiment in particle physics aiming to detect "neutrino-less double beta decay" using large amounts of xenon isotopically enriched in the isotope 136. A 200-kg detector using liquid Xe is currently being installed at the Waste Isolation Pilot Plant (WIPP) near Carlsbad, New Mexico. Many research and development efforts are underway for a ton-scale experiment, with the goal of probing new physics and the mass of the neutrino. The Enriched Xenon Observatory

    Feynman diagram of neutrinoless double-beta decay, with two neutrons decaying to two protons. The only emitted products in this process are two electrons, which can only occur if the neutrino and antineutrino are the same particle (i.e. Majorana neutrinos) so the same neutrino can be emitted and absorbed within the nucleus. In conventional double-beta decay, two antineutrinos - one arising from each W vertex - are emitted from the nucleus, in addition to the two electrons. The detection of neutrinoless double-beta decay is thus a sensitive test of whether neutrinos are Majorana particles.

    Numerous experiments have been carried out to search for neutrinoless double-beta decay. Some recent and proposed future experiments include:

    Permanence of Fact in Literature

    John Updike in 1955.
    John Hoyer Updike (18 March 1932 – 27 January 2009) was an American novelist, poet, short story writer, art critic, and literary critic. Updike's most famous work is his Rabbit series (Rabbit, Run; Rabbit Redux; Rabbit Is Rich; Rabbit At Rest; and Rabbit Remembered). Both Rabbit is Rich and Rabbit at Rest received the Pulitzer Prize. Describing his subject as "the American small town, Protestant middle class," Updike was widely recognized for his careful craftsmanship, his highly stylistic writing, and his prolific output, having published more than twenty-five novels and more than a dozen short story collections, as well as poetry, art criticism, literary criticism and children's books. Hundreds of his stories, reviews, and poems appeared in The New Yorker, starting in 1954. He also wrote regularly for The New York Review of Books. His work attracted a significant amount of critical attention and he was considered one of the most prominent contemporary American novelists.[2] Updike died of lung cancer on January 27, 2009.

    Current knowledge and scientific discovery help to align our thinking. They help us to recognize what had been "set in stone" in literature, as a passing thought in that day of poetry creation. So every progression in terms of knowledge has it's predecessors, and from that, the old and the new contrast each other. We know a little more.

    Cosmic Gall by John Updike-Telephone Poles and Other Poems, Knopf, 1960 


    Neutrinos they are very small.
    They have no charge and have no mass
    and do not interact at all.
    The earth is just a silly ball
    To them, through which they simply pass,
    Like dustmaids down a drafty hall
    Or photons through a sheet of glass.
    They snub the most exquisite gas,
    Ignore the most substantial wall,
    Cold-shoulder steel and sounding brass,
    Insult the stallion in his stall,
    And, scorning barriers of class,
    Infiltrate you and me! Like tall
    And painless guillotines, they fall
    Down through our heads into the grass.
    At night, they enter at Nepal
    And pierce the lover and his lass
    From underneath the bed – you call
    It wonderful; I call it crass.

    STATEMENT: EVIDENCE FOR MASSIVE NEUTRINOS FOUND by Dave Casper

    Cerenkov Radiation
    By classifying the neutrino interactions according to the type of neutrino involved (electron-neutrino or muon-neutrino) and counting their relative numbers as a function of the distance from their creation point, we conclude that the muon-neutrinos are "oscillating." Oscillation is the changing back and forth of a neutrino’s type as it travels through space or matter. This can occur only if the neutrino possesses mass. The Super-Kamiokande result indicates that muon-neutrinos are disappearing into undetected tau-neutrinos or perhaps some other type of neutrino (e.g., sterile-neutrino). The experiment does not determine directly the masses of the neutrinos leading to this effect, but the rate of disappearance suggests that the difference in masses between the oscillating types is very small. The primary result that we are reporting has a statistical significance of more than 5 standard deviations. An independent measurement based on upward-going muons in the detector confirms the result at the level of more than 3 standard deviations.

    Galactic Neutrino Communications

    Galactic Neutrino Communication by John G. Learned, Sandip Pakvasa, A. Zee

    We examine the possibility to employ neutrinos to communicate within the galaxy. We discuss various issues associated with transmission and reception, and suggest that the resonant neutrino energy near 6.3 PeV may be most appropriate. In one scheme we propose to make Z^o particles in an overtaking e^+ - e^- collider such that the resulting decay neutrinos are near the W^- resonance on electrons in the laboratory. Information is encoded via time structure of the beam. In another scheme we propose to use a 30 PeV pion accelerator to create neutrino or anti-neutrino beams. The latter encodes information via the particle/anti-particle content of the beam, as well as timing. Moreover, the latter beam requires far less power, and can be accomplished with presently foreseeable technology. Such signals from an advanced civilization, should they exist, will be eminently detectable in neutrino detectors now under construction.


    I though I'd better fill in the spots about leaving comments in places, and not showing the significance of what I am pointing to by insinuation alone.

    However, Kapusta also notes that a sufficiently advanced civilization might use pulses of neutrino superfluid for long-distance communications.
    See:Cern Courier:The right spin for a neutrino superfluid



    This of course requires that we look at what Joe Kapusta is actually doing at Cern. A comment that is "slight of hand," that shows what I am pointing too, is at the forefront of what is to come out of Cern at startup, along with the benefits of the Muon detection.

    Well you had to know, left to my own devices, the ability to pick out the information that is setting the course for humanities future, is of course great interest to me. What descending people may see of this blog, or the "tightening of the circle" against the influences from here, is of course a close mindedness that always comes at a cost. The abilities I may harbour in other areas are less of a concern to me, knowing that what I am sharing is always the work at the edges of the periphery of our vision.

    Vernon Barger: perspectives on neutrino physics Posted by dorigo

    Barger then mentioned the idea of mapping the universe with neutrinos: the idea is that active galactic nuclei (AGN) produce hadronic interactions with pions decaying to neutrinos, and there is a whole range of experiments looking at this. You could study the neutrinos coming from AGN and their flavor composition.


    So you look at the universe in "different ways" and never before had you thought to think that the constrains that are applied to self, is the limitation we settle our own points of view too. These are the "resounding factors" that work "like a Higgs" as these things gather around it. Life gathers around that "point of view." You've set the tone. Brain Cox on Ted.com, gives a nice example of Margaret Thatcher moving across the room.

    I do not know how many times I can use the word like "tone" and not have found some relevance to the psychology of the individual, and then, see it's relation out there in terms of the Lagrangian. HelioSeismology's(see sidebar and click on sun, or, other abstract picture) and how it that we can predict such events within the very sun itself and by use of SOHO. This gives us an advantage and a warning system in place in relation to sunspot activity.

    Ruffles in the Field

    So easy then to speak on the significance of the emotive struggle, and then not to find a relation to the space around us. The context of gathering thoughts and things, as they are defined as some graviton gathering in a bulk perspective of space?

    Why I glamour to the cause of those who hurt the attempts to see the world in different ways, and leave people to prognosticate to their own devices and to the call of, "let there be dragons." Gathered around then to the limitations of the thinking mind, set by others. We want people to push these boundaries, not be limited by them.



    This picture is a copy of a "16 century woodcut" copied by Camille Flammarion in 1888.


    The Flammarion woodcut. Flammarion's caption translates to "A medieval missionary tells that he has found the point where heaven and Earth meet..."
    The widely circulated woodcut of a man poking his head through the firmament of a flat Earth to view the mechanics of the spheres, executed in the style of the 16th century cannot be traced to an earlier source than Camille Flammarion's L'Atmosphère: Météorologie Populaire (Paris, 1888, p. 163) [38]. The woodcut illustrates the statement in the text that a medieval missionary claimed that "he reached the horizon where the Earth and the heavens met", an anecdote that may be traced back to Voltaire, but not to any known medieval source. In its original form, the woodcut included a decorative border that places it in the 19th century; in later publications, some claiming that the woodcut did, in fact, date to the 16th century, the border was removed. Flammarion, according to anecdotal evidence, had commissioned the woodcut himself. In any case, no source of the image earlier than Flammarion's book is known.
    See here for larger version "with caption" that has been translated above.

    Pushing back the veil of our boundaries of thought are always of interest to me and the woodcut while speculated upon is my way of expressing this attempt.

    The CrossOver Point within the Perfect Fluid?

    I had been following this research because of what I had been trying to understand when we take our understanding down to a certain level. That level is within the context of us probing the collision process for evidence of "some new physics" that we had not seen before.

    Evidence for Neutrino Oscillations from the LSND Experiment
    One of the only ways to probe small neutrino masses is to search for neutrino oscillations, where a neutrino of one type (e.g. numubar ) spontaneously transforms into a neutrino of another type (e.g. nuebar ) For this phenomenon to occur, neutrinos must be massive and the apparent conservation law of lepton families must be violated. The probability for 2-flavor neutrino oscillations can then be expressed as P=sin2(2theta) sin2(1.27 m2L/E) , where theta is the mixing angle, m2 is the difference in neutrino masses squared in eV2, L is the neutrino distance in meters, and E is the neutrino energy in MeV. In 1995 the LSND experiment [1] published data showing candidate events that are consistent with numubar->nuebar oscillations. [2] Additional data are reported here that provide stronger evidence for numubar->nuebar oscillations [3] as well as evidence for numu->nue oscillations. [4] The two oscillation searches have completely different backgrounds and systematics from each other.


    What valuation of this process allows us to think that while speaking to "probing this perfect fluid" that we had not discovered some mechanism within it, that allows us to see Coleman Mandula effects being behind, as a geometrical unfoldment from one state into another?

    If we had looked at the Genus 1 figure then what avenue would help us discern what could come from the string theory landscape and the "potential hill" discerned from the blackhole horizon? What tunnelling effect could go past the hill climbers and valley crossers to know that you could cut "right through the hill?"

    MiniBooNE opens the box

    BATAVIA, IllinoisScientists of the MiniBooNE1 experiment at the Department of Energy's Fermilab2 today (April 11) announced their first findings. The MiniBooNE results resolve questions raised by observations of the LSND3 experiment in the 1990s that appeared to contradict findings of other neutrino experiments worldwide. MiniBooNE researchers showed conclusively that the LSND results could not be due to simple neutrino oscillation, a phenomenon in which one type of neutrino transforms into another type and back again.

    The announcement significantly clarifies the overall picture of how neutrinos behave.


    So while I am looking for some indications as I did in the strangelet case, as, evidence of this crossover, this had to have some relation to how we seen the neutrinos in development. This was part of the development as we learnt of the history of John Bahcall.

    the quark-gluon plasma behaves according to hydrodynamic calculations in which the matter is like a liquid that flows with no viscosity whatsoever.” See here

    No cross over point? What role would Navier Stokes play in this?
    See here

    This does not minimize the work we see of Gran Sasso in relation to the LHC project.

    Honestly, I do not know how someone who could work on the project, could not know what they were working on? It as if the "little parts" of the LHC project only cater to the worker Bees working just aspects of the project and their specializations.

    Whilst now, you go way up and overlook this project. To see the whole context measured within that "one tiny big bang moment." Trust me when I say, we shall not minimize the effect of calling the collision process as "one tiny moment," for you may never see the whole context of this project being developed for this "one thing."

    I did not realize the shortcomings that scientists place on themselves when they do specialize. I just assumed they would know as much as I did and see the whole project? I do not say this unkindly, just that it is a shock to me that one could work the string theory models and not realize what they are working on. I have heard even Jacques say there is no connection and listening to Peter Woit, I was equally dismayed that he did not realize what the string theory model was actually doing as it found it's correlation in the developing views of how we look at the moments of creation.

    Bigger is better if you’re searching for smaller

    Neutrinos may be in CERN's Future

    The next step will again be taken in Japan, with the new J-PARC accelerator starting in 2009 to send neutrinos almost 300 km, again to the Super-Kamiokande experiment, to probe the third neutrino mixing angle that has not yet been detected in either atmospheric or solar neutrino experiments. This may also be probed in a new experiment being proposed for the Fermilab NuMI beam. One of the ideas proposed at CERN is to probe this angle with an underwater experiment moored in the Gulf of Taranto off the coast of Italy, viewing neutrinos in a modified version of CERN's current Gran Sasso beam.

    I think my comment on previous post of looking for the perfect fluid should have been here.

    Also I do not think this changes how we look at string theory as a model probing the perfect fluid, and "the understanding" of developing a mechanism for this "cross over point?"

    Topologically, how would this have been revealed in the string theory landscape??
    See here and know that Clifford again deleted the short little post above. The point is I think for some reason once I mention string theory or evn M theory in relation to what is transpiring in the views of model development he doe not like this and would be support by Jacques as well.

    That would be my job to convince them and anyone else that hold their views that taking our view to the microseconds, there is a definite relation to the timeline whether you agree with this or not. By introducing "the point of the cross over" you in effect have taken the model and presented it as part of the mechanism for this universe and effectively given new meaning to the "string theory landscape."

    You may want it to be "background independent" like Lee wants it to be, but if you view the background as a oscillatory one, then any idea as configured to the mass of any particle, then you have define this particle as a energy relation? So Lee does not like the oscillatory universe?

    See "Finiteness of String Theory and Mandelstam"

    It is contained "within the moment" of the creation of this universe, yet, we do not know what design this particle is to be in context of the microscopic view of geometrical topologically finishes? As the Genus 1 figure and as an expression of this universe? You had to know what was lying in those valleys, and the potentials of expression, and I relay that in the blackhole horizon as a potential hill.

    The time has come for some changes in this blog and I have been thinking about moving on. While a layman, I do not like to be treated like a fool. Maybe not educated fully and with some work to do, but never as a fool.

    Blackhole evaporation: What's New From the Subatomic-Sized Holes ?

    ...the creative principle resides in mathematics. In a certain sense therefore, I hold it true that pure thought can grasp reality, as the ancients dreamed.Albert Einstein
    See What is Cerenkov Radiation?

    We are being "politically correct" (a sociological observation) when we change the wording of the "microstate blackhole production" to "Sub Atomic Sized Holes?" To maybe "inferr" the desired differences of cosmological blackholes, versus, what we see quickly evaporating in subatomic-sized to be revealed in a footprint?

    David Kestenbaum, NPR-Alvaro De Rujula is a physicist at CERN, the world's largest particle physics laboratory. Three hundred feet below his desk, workers are building a massive particle accelerator that will be capable of reproducing energies present just after the big bang.

    Let's pretend that the reporting was not so good back in 1999, and the information we had then was to cause some needless concerns? Good reporting already existed in term of what the Dark Matter was doing. Now it's okay if someone else saids it, and reveals all the dark matter info with Wikipedia. How nice:)Your credible?

    Was there any evidence to think a method was already determined "back then" and has become part of the process of discovery?

    Bad reporting?

    At first bad reporting? Producing fear into the public mind?

    In recent years the main focus of fear has been the giant machines used by particle physicists. Could the violent collisions inside such a machine create something nasty? "Every time a new machine has been built at CERN," says physicist Alvaro de Rujula, "the question has been posed and faced." August 1999

    Peter Steinberg, when at Quantum diaries, lead us through this.

    The creepy part of these kind of discussions is that one doesn't say that RHIC collisions "create" black holes, but that nucleus-nucleus collisions, and even proton-proton collisions, are in some sense black holes, albeit black holes in some sort of "dual" space which makes the theory easier.


    Alvaro was the one who put "James Blodgett of Risk assessment" at ease in regards to strangelets. Now, could strangelets have been considered a consequence of the evaporation? Does this not look similar?

    deconstruction: event display
    Usually all physicists see are the remnants of a new particle decaying into other types of particles. From that, they infer the existence of the new species and can determine some of its characteristics.
    SeeNeutrino Mixing Explained in 60 seconds

    Now everything is safe and cozy with these subatomic-sized holes which would simply evaporate. :) How would you know "what is new" after the subatomic holes had evaporated? Are sterile neutrinos new?

    While these paragraphs have been selective, they show that experimental processes are being used and detective work applied.

    Current evidence shows that neutrinos do oscillate, which indicates that neutrinos do have mass. The Los Alamos data revealed a muon anti-neutrino cross over to an electron neutrino. This type of oscillation is difficult to explain using only the three known types of neutrinos. Therefore, there might be a fourth neutrino, which is currently being called a "sterile" neutrino, which interacts more weakly than the other three neutrinos.

    Any add on experimental processes at Cern with regards to the LHC are reflect in this second paragraph?

    "We find," Chiao said, "that a barrier placed in the path of a tunneling particle does not slow it down. In fact, we detect particles on the other side of the barrier that have made the trip in less time than it would take the particle to traverse an equal distance without a barrier -- in other words, the tunnelling speed apparently greatly exceeds the speed of light. Moreover, if you increase the thickness of the barrier the tunneling speed increases, as high as you please.

    See Gran Sasso

    So while one may think I have some "new process" to make the world happy, it is nothing of the sort. It is interpreting the current theoretical models in regards to current experimental research.

    For some reason some scientist think that one can be devoid of this reasoning and apply it to any model/person, while the scientist/lay people already know what is required.

    This has been reflected time and again through the interactions of scientist with the public. What is one to think when one scientist calls another scientists devoid of such reason, while he works to develop the string theory model. They don't like that do they?:)


    So do you think that Clifford of Asymptotia is practising what he did not like in Peter Woit's summation of the state of affairs in string theory? That while criticizing him he was doing the same thing to others? I laughed when I came across the censoring post on Not even Wrong, and why I had to write my new article on Censoring.

    I have never seen such "happy trigger fingers" as to deletion of posts that would contradict the statements Clifford could make about another person, or what Peter Woit could say about "Clifford censoring" statements. Peter provides a forum for those who feel shafted who could voice there displeasure?:)

    Don't worry Peter I certainly won't be crying on your blog. Deletion knows it boundaries in terms of censoring there too.:) But anyway, onto the important stuff.

    This summer, CERN gave the starting signal for the long-distance neutrino race to Italy. The CNGS facility (CERN Neutrinos to Gran Sasso), embedded in the laboratory's accelerator complex, produced its first neutrino beam. For the first time, billions of neutrinos were sent through the Earth's crust to the Gran Sasso laboratory, 732 kilometres away in Italy, a journey at almost the speed of light which they completed in less than 2.5 milliseconds. The OPERA experiment at the Gran Sasso laboratory was then commissioned, recording the first neutrino tracks. See Strangelets and Strange Matter

    Tunnelling in the string theory landscape

    Now it may not seem so odd that I would place a string theory landscape picture up for revue, and have one think about hill climbers and valley crossers. Would it be wrong not to include the "potential hills" and the thought of the "blackhole horizon?" It was "theoretical appealing" as a thought experiment to me, to think about what could traverse those potential hills. We had to use "a mechanism" to help us understand how the cross over point was being established and "new universes" begin to unfold? New particle creation from such collision processes had to be established first. Both at Cern and with "high energy particles from space." IceCube was to be the backdrop for the footprint, and resulting Cerenkov radiation from that collision process?

    One needed to see such experiment as taking place currently to help us see the jest of where science is currently taking us on our journey's. So you had to be able to see this process in action back to the insecurities of our ignorance, in relation too, sub-atomic sized holes...ahem...dualites?

    So you had to know that the collision process would detail some "crossover point" for consideration? What this means that "after the collision process" you are given a new particle with which to work.

    You need to be able to capture this "new particle" and the mediums with which this is done, are the barriers that supply the back drop for foot prin,t to what can be traversed in faster then light potentials. Again Gran Sasso, and let's not forget ICECUBE.

    Cross over point

    Is it not important to see the experimental process as a natural one?

    Bringing the Heavens down to Earth

    If mini black holes can be produced in high-energy particle interactions, they may first be observed in high-energy cosmic-ray neutrino interactions in the atmosphere. Jonathan Feng of the University of California at Irvine and MIT, and Alfred Shapere of the University of Kentucky have calculated that the Auger cosmic-ray observatory, which will combine a 6000 km2 extended air-shower array backed up by fluorescence detectors trained on the sky, could record tens to hundreds of showers from black holes before the LHC turns on in 2007. See here


    So here we are talking about the "before" and "after" and we had not spoken about the point of exchange here? If I were to tell you that such a reductionistic process had taken us to the limits what the heck could this mean? That we had indeed found the transference point of energy to matter, matter to energy and we say it may be the perfect fluids that supplies us this "anomalistic behaviour" with which we will introduce the GR? Talk about Navier-stokes in relation to the perfect fluid and what and how something can traverse through and come out on the other side?

    Neutrino Mixing Explained in 60 seconds

    I added this post to demonstrate the connection to what is behind the investigation to "neutrino mixing" that needs further clarification. So I put this blog post together below.

    It "allows the sources" to consider the question of how we see the existing universe. How perspective has been focused toward the reductionist understanding while we ponder the very nature of the universe.



    For example, when neutrinos interact with matter they produce specific kinds of other particles. Catch the neutrino at one moment, and it will interact to produce an electron. A moment later, it might interact to produce a different particle. "Neutrino mixing" describes the original mixture of waves that produces this oscillation effect.


    By my very nature, I have adopted the views of the Pythagoreans in that, what I see of the universe has it's counter part as some feature within our determinations "as the background" to the "nature of all matter." It's effect, from understanding the very basis of "particle creation" has this factor to be included in our determinations of that particle in question.

    So, what views shall we assign to the Higg's Boson Field? The view of the cosmos at large? We needed to see that such events can and do happen within the universe. To see them at a level that had not been considered in terms of the microstate blackhole creation that is created from such particle collisions? One needed to identify where "these points" could exist not only in the collider, but in the cosmos at large. How else could you explain the division you have assigned the make up of the cosmos?



    Usually all physicists see are the remnants of a new particle decaying into other types of particles. From that, they infer the existence of the new species and can determine some of its characteristics.


    So we move from the limitations of the standard model?

    This is a fixture of what has been accomplished, yet, how could we see things as so different to include gravity as a feature and new force carrier? If we are to consider the energy of all these matters, then how else could you have included gravity?



    To slow them down, theorists proposed a mysterious, universe-filling, not-yet-seen "liquid" called the Higgs field. Also, physicists now understand that 96 percent of the universe is not made of matter as we know it, and thus it does not fit into the Standard Model. How to extend the Standard Model to account for these mysteries is an open question to be answered by current and future experiments.


    While it is some what mysterious, the applications as ancient as they may seem, they are not apart from our constitutions as we have applied our understanding of the universe it seems:)

    Radiactive Decay

    Unit Circle


    Complex numbers can be identified with points in the Euclidean plane, namely the number a + bi is identified with the point (a, b). Under this identification, the unit circle is a group under multiplication, called the circle group. This group has important applications in mathematics and science. See here.

    Just briefly showing containment of "collision process" and for later study. This is how I see this "relation of cosmic particle collisions" to incidents in "high energy collisions processes" and I wonder if this is wrong? Also pointing toward "Neutrino oscillation" as a probabilistic consequence of Quantum mechanics.

    To the Substance of this Post

    Q9 raised an issue that is of some significance to me because of the way I was "geometrically seeing these collision processes." While, I had not moved my thinking to the human factor in this process, it has in my study raised the question of what effect it has on the human populations on a personal note.

    Quasar9:
    The general effects of radon to the human body are due to its radioactivity and consequent risk of radiation-induced cancer. As an inert gas, "radon has a low solubility in body fluids which lead to a uniform distribution of the gas throughout the body" (Lindgren, 1989). Radon gas and its solid decay products are carcinogens. Some of the daughter products, especially polonium-218 and 214, from radioactive decay of radon present a radiologic hazard. Depending on the size of the particles, radon decay products can be inhaled into the lung where they undergo further radioactive decay releasing small bursts of energy in the form of alpha particles that can either cause double strand DNA breaks or create free radicals that can also damage the DNA. Also See: Radon





    The ABCs - and Xs and Zs - of Radiation

    Alpha and beta rays are particles. Gamma rays are electromagnetic radiation, like X-rays but at higher energies. Health physicists worry most about HZE cosmic rays, those with high mass (Z stands for atomic number, which also implies mass) and energy (E). They have two principal sources, the Sun and the galaxy.


    Quasar9:
    The energy of alpha particles varies, with higher energy alpha particles being emitted from larger nuclei, but most alpha particles have energies of between 3 and 7 MeV. This is a substantial amount of energy for a single particle, but their high mass means alpha particles have a lower speed (with a typical kinetic energy of 5 MeV the speed is 15,000 km/s) than any other common type of radiation (β particles, γ-rays, neutrons etc). Because of their charge and large mass, alpha particles are easily absorbed by materials and can travel only a few centimetres in air. They can be absorbed by tissue paper or the outer layers of human skin (about 40 micrometres, equivalent to a few cells deep) and so are not generally dangerous to life unless the source is ingested or inhaled. Because of this high mass and strong absorption, however, if alpha radiation does enter the body (most often because radioactive material has been inhaled or ingested), it is the most destructive form of ionizing radiation. It is the most strongly ionizing, and with large enough doses can cause any or all of the symptoms of radiation poisoning. It is estimated that chromosome damage from alpha particles is about 100 times greater than that caused by an equivalent amount of other radiation. The alpha emitter polonium-210 is suspected of playing a role in lung and bladder cancer related to tobacco smoking. Also See:Alpha Particles



    Low energy alpha particles may be completely stopped by a sheet of paper, beta particles by aluminum shielding. Gamma rays, being very high energy in nature, can only be reduced by much more substantial obstacles, such as a very thick piece of lead.

    As for types of radioactive radiation, it was found that an electric or magnetic field could split such emissions into three types of beams. For lack of better terms, the rays were given the alphabetic names alpha, beta, and gamma, names they still hold today. It was immediately obvious from the direction of electromagnetic forces that alpha rays carried a positive charge, beta rays carried a negative charge, and gamma rays were neutral. From the magnitude of deflection, it was also clear that alpha particles were much more massive than beta particles. Passing alpha rays through a thin glass membrane and trapping them in a discharge tube allowed researchers to study the emission spectrum of the resulting gas, and ultimately prove that alpha particles are in fact helium nuclei. Other experiments showed the similarity between beta radiation and cathode rays; they are both streams of electrons, and between gamma radiation and X-rays, which are both high energy electromagnetic radiation.

    Although alpha, beta, and gamma are most common, other types of decay were eventually discovered. Shortly after discovery of the neutron in 1932, it was discovered by Enrico Fermi that certain rare decay reactions give rise to neutrons as a decay particle. Isolated proton emission was also eventually observed in some elements. Shortly after the discovery of the positron in cosmic ray products, it was realized that the same process that operates in classical beta decay can also produce positrons (positron emission), analogously to negative electrons. Each of the two types of beta decay acts to move a nucleus toward a ratio of neutrons and protons which has the least energy for the combination. Finally, in a phenomenon called cluster decay, specific combinations of neutrons and protons other than alpha particles were found to occasionally spontaneously be emitted from atoms.

    Tunnelling in Faster then Light

    Underneath this speculation of mine is the geometrical inclination of the universe in expression. If it's "dynamical nature is revealed" what allows us to think of why this universe at this time and junction, should be flat(?) according to the time of this universe in expression?

    Omega=the actual density to the critical density

    If we triangulate Omega, the universe in which we are in, Omegam(mass)+ Omega(a vacuum), what position geometrically, would our universe hold from the coordinates given?


    Positive energy density gives spacetime of the universe a positive curvature. A sphere? Negative curvature a region of spacetime that is negative and curved like a saddle? For time travel, and travel into the past, you need a universe that has a negative energy density.

    Thus the initial idea here to follow is that the process had to have a physics relation. This is based on the understanding of anti-particle/particle, and what becomes evident in the cosmos as a closed loop process. Any variation within this context, is the idea of "blackhole anti-particle expression" based on what can be seen at the horizon?



    A anti-particle can be considered as a particle moving back in time? Only massless particle can travel faster then light. Only faster then light massless particles can travel back in time? So of course, I am again thinking of the elephant process of Susskind and the closed loop process of the virtual particle/anti-particle. What comes out of it?

    That's not all. The fact that space-time itself is accelerating - that is, the expansion of the universe is speeding up - also creates a horizon. Just as we could learn that an elephant lurked inside a black hole by decoding the Hawking radiation, perhaps we might learn what's beyond our cosmic horizon by decoding its emissions. How? According to Susskind, the cosmic microwave background that surrounds us might be even more important than we think. Cosmologists study this radiation because its variations tell us about the infant moments of time, but Susskind speculates that it could be a kind of Hawking radiation coming from our universe's edge. If that's the case, it might tell us something about the elephants on the other side of the universe.


    So the anti-particle falls into the blackhole? How is it that I resolve this?? You can consider the anti-particle as traveling back in time. The micro perspective of the blackhole allows time travel backwards.


    Getty Images
    Although a 1916 paper by Ludwig Flamm from the University of Vienna [4] is sometimes cited as giving the first hint of a wormhole, "you definitely need hindsight to detect it," says Matt Visser of Victoria University in Wellington, New Zealand. Einstein and Rosen were the first to take the idea seriously and to try to accomplish some physics with it, he adds. The original goal may have faded, but the Einstein-Rosen bridge still pops up occasionally as a handy solution to the pesky problem of intergalactic travel.


    There are two cases in which the thoughts about faster then light particles are created and this is the part where one tries to get it right so as not to confuse themselves and others.

    Wormholes?

    Plato:
    So "open doorways" and ideas of "tunneling" are always interesting in terms of how we might look at an area like GR in cosmology? Look for way in which such instances make them self known.

    Are they applicable to the very nature of quantum perceptions that such probabilities could have emerged through them? Held to "time travel scenarios" and grabbed the history of what had already preceded us in past tense, could have been brought again forward for inspection?


    Sure I am quoting myself here, just to show one of the options I am showing by example. The second of course is where I was leading too in previous posts.

    So I was thinking here in context of one example in terms of the containment of the "graviton in a can" is really letting loose of the information in the collision process, as much as we like this "boundary condition" it really is not so.

    Another deep quantum mystery for which physicists have no answer has to do with "tunneling" -- the bizarre ability of particles to sometimes penetrate impenetrable barriers. This effect is not only well demonstrated; it is the basis of tunnel diodes and similar devices vital to modern electronic systems.

    Tunneling is based on the fact that quantum theory is statistical in nature and deals with probabilities rather than specific predictions; there is no way to know in advance when a single radioactive atom will decay, for example.

    The probabilistic nature of quantum events means that if a stream of particles encounters an obstacle, most of the particles will be stopped in their tracks but a few, conveyed by probability alone, will magically appear on the other side of the barrier. The process is called "tunneling," although the word in itself explains nothing.

    Chiao's group at Berkeley, Dr. Aephraim M. Steinberg at the University of Toronto and others are investigating the strange properties of tunneling, which was one of the subjects explored last month by scientists attending the Nobel Symposium on quantum physics in Sweden.

    "We find," Chiao said, "that a barrier placed in the path of a tunneling particle does not slow it down. In fact, we detect particles on the other side of the barrier that have made the trip in less time than it would take the particle to traverse an equal distance without a barrier -- in other words, the tunneling speed apparently greatly exceeds the speed of light. Moreover, if you increase the thickness of the barrier the tunneling speed increases, as high as you please.

    "This is another great mystery of quantum mechanics."


    Of course I am looking for processes in physics that would actually demonstrate this principal of energy calculated at the very beginning of the collision process, now explained in the detector, minus the extra energy that had gone where?



    This is the basis for the "Graviton in a can" example of what happens in the one scenario.

    Plato:
    A Bose-Einstein condensate (such as superfluid liquid helium) forms for reasons that only can be explained by quantum mechanics. Bose condensates form at low temperature


    Plasmas and Bose condensates

    So in essence the physics process that I am identifying is shown by understanding that the "graviton production" allows that energy to be transmitted outside the process of the LHC?

    This is the energy that can be calculated and left over from all the energy assumed in the very beginning of this collision process. Secondly, all energy used in this process would be in association with bulk perspective.

    This now takes me to the second process of "time travel" in the LHC process. The more I tried to figure this out the basis of thought here is that Cerenkov radiation in a vacuum still is slower then speed of light, yet within the medium of ice, this is a different story. So yes there are many corrections and insight here to consider again.

    The muon will travel faster than light in the ice (but of course still slower than the speed of light in vacuum), thereby producing a shock wave of light, called Cerenkov radiation. This light is detected by the photomultipliers, and the trace of the neutrinos can be reconstructed with an accuracy of a couple of degrees. Thus the direction of the incoming neutrino and hence the location of the neutrino source can be pinpointed. A simulation of a muon travelling through AMANDA is shown here (1.5 MB).


    So while sleeping last night the question arose in my mind as to the location of where the "higgs field" will be produced in the LHC experiment? Here also the the thoughts about the "cross over point" that would speak to the idea here of what reveals faster then light capabilities arising from the collision process?

    What are the main goals of the LHC?-
    The LHC will also help us to solve the mystery of antimatter. Matter and antimatter must have been produced in the same amounts at the time of the Big Bang. From what we have observed so far, our Universe is made of only matter. Why? The LHC could provide an answer.

    It was once thought that antimatter was a perfect 'reflection' of matter - that if you replaced matter with antimatter and looked at the result in a mirror, you would not be able to tell the difference. We now know that the reflection is imperfect, and this could have led to the matter-antimatter imbalance in our Universe.

    The strongest limits on the amount of antimatter in our Universe come from the analysis of the diffuse cosmic gamma-rays arriving on Earth and the density fluctuations of the cosmic background radiation. If one asumes that after the Big Bang, the Universe separated somehow into different domains where either matter or antimatter was dominant, then at the boundaries there should be annihilations, producing cosmic gamma rays. In both cases the limit proposed by current theories is practically equivalent to saying that there is no antimatter in our Universe.


    So we get the idea here in the collision process and from it the crossover point leaves a energy dissertation on what transpired from this condition and left the idea in my mind about the circumstances of what may have changed the the speed of the cosmos at varying times in the expansion process within our universe. So, this is where I was headed as I laid out the statement below.

    Of course this information is based on 2003 data but the jest of the idea here is that in order to go to a "fast forward" the conditions had to exist previously that did not included "sterile neutrinos" and were a result of this "cross over."


    So what is the jest of my thought here that I would go to great lengths here to speak about the ideas of what happens within the cosmos to change those varying times of expansion? It has to do with the Suns and the process within those suns that give the dark energy some value, in it's anti- gravity nature to align our selves and our thinking to the cosmological constant of Einstein. If we juggle the three ring circus we find that the curvature parameters can and do hold thoughts govern by the cosmological constant?

    It is thus equally important to identify this "physics process" that would allow such changes in the cosmos. So that we can understand the dynamical nature that the cosmos reveals to us can and does allow aspect of its galaxies within context of the universe to increase this expansive process while we question what drives such conditions.
