Performance of t-lepton reconstruction and identification in CMS
The performance of τ-lepton reconstruction and identification algorithms is studied using a data sample of proton-proton collisions at √ s = 7 TeV, corresponding to an integrated luminosity of 36 pb−1 collected with the CMS detector at the LHC. The τ leptons that decay into one or three charged hadr...

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