"Performance of τ-lepton reconstruction and identification in CMS." <i>Journal of Instrumentation,</i> 7, (2012) IOP Publishing: P01001. http://dx.doi.org/10.1088/1748-0221/7/01/P01001.https://hdl.handle.net/1911/80959The 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.engContent may be used under the terms of the Creative Commons Attribution-Non-Commercial-ShareAlike 3.0 license.
