Abstract
Identification of jets originating from beauty and charm quarks is important for measuring Standard Model processes and for searching for new physics. The performance of algorithms developed to select b- and c-quark jets is measured using data recorded by LHCb from proton-proton collisions at s√=7 TeV in 2011 and at s√=8 TeV in 2012. The efficiency for identifying a b(c) jet is about 65%(25%) with a probability for misidentifying a light-parton jet of 0.3% for jets with transverse momentum pT>20 GeV and pseudorapidity 2.2<η<4.2. The dependence of the performance on the pT and η of the jet is also measured.
