摘要:	摘要： This paper describes the algorithms used by the CMS experiment to reconstruct and identify tau to hadrons + tau decays during Run 1 of the LHC. The performance of the algorithms is studied in proton-proton collisions recorded at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.7 inverse femtobarns. The algorithms achieve an identification efficiency of 50-60%, with misidentification rates for quark and gluon jets, electrons, and muons between per mille and per cent levels. 出版者： IOP Publishing 出版日期： 2016 出處： Journal of instrumentation, 2016, Vol.11 資源來源： Institute of Physics Journals 版權： CC0 1.0 - Universal 識別號： ISSN: 1748-0221 識別號： EISSN: 1748-0221 識別號： DOI: 10.1088/1748-0221/11/01/P01019
