CSIC ORCID; CMS Collaboration | Fecha de publicación: | 2012 | Editor: | Institute of Physics Publishing | Citación: | Journal of Instrumentation 7: P01001 (2012) | Resumen: | 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. | Descripción: | Open Access under the terms of the Creative Commons Attribution-Non-Commercial-ShareAlike 3.0 license.-- Chatrchyan, S. et al. | Versión del editor: | http://dx.doi.org/10.1088/1748-0221/7/01/P01001 | URI: | http://hdl.handle.net/10261/52040 | DOI: | 10.1088/1748-0221/7/01/P01001 | Identificadores: | doi: 10.1088/1748-0221/7/01/P01001 e-issn: 1748-0221 |
