Algorithms are defined to identify such W jets for different signals of interest, using techniques that are also applicable to other decays of bosons to hadrons that result in a single jet, such as those from highly boosted Z and Higgs bosons. The efficiency for tagging W jets is measured in data collected with the CMS detector at a center-of-mass energy of 8TeV, corresponding to an integrated luminosity of 19.7 fb(-1). The performance of W tagging in data is compared with predictions from several Monte Carlo simulators.eninfo:eu-repo/semantics/openAccessJetsJet physicsHadron-Hadron ScatteringArticle12WOS:0003496000000012-s2.0-8491468927610.1007/JHEP12(2014)017Q1Q1
