Abstract
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 s = 7 TeV. The search is performed for associated production of a lepton and an oppositely charged excited lepton pp * , followed by the decay * , resulting in the final state, where = e, . 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.
