 A search for excited leptons in pp collisions at ps = 7 TeV

 

A search for excited leptons is carried out with the CMS detector at the LHC, using
36 pb��1 of pp collision data recorded at ps = 7 TeV. The search is performed for associated
production of a lepton and an oppositely charged excited lepton pp ! `` ,
followed by the decay ` ! `g, resulting in the ``g final state, where ` = e, m. No
excess of events above the standard model expectation is observed. Interpreting the
findings in the context of ` production through four-fermion contact interactions and
subsequent decay via electroweak processes, first upper limits are reported for ` production
at this collision energy. The exclusion region in the compositeness scale L and
excited lepton mass M` parameter space is extended beyond previously established
limits. For L = M` , excited lepton masses are excluded below 1070 GeV/c2 for e
and 1090 GeV/c2 for m at the 95% confidence level.
