Sažetak
The performance of t -lepton reconstruction and identification algorithms is studied using a data sample of proton-proton collisions at p s = 7 TeV, corresponding to an integrated lu- minosity of 36 pb 1 collected with the CMS detector at the LHC. The t leptons that decay into one or three charged hadrons, zero or more short-lived neutral hadrons, and a neutrino are identi- fied using final-state particles reconstructed in the CMS tracker and electromagnetic calorimeter. The reconstruction efficiency of the algorithms is measured using t leptons produced in Z-boson decays. The t -lepton misidentification rates for jets and electrons are determined.
