Identification of beauty and charm quark jets at LHCb Badalov, Alexey Casanova Mohr, Raimon Garrido Beltrán, Lluís Gascón Fora, David Graciani Díaz, Ricardo Graugés Pous, Eugeni Marin Benito, Carla Picatoste Olloqui, Eduardo Rives Molina, Vicente José Ruiz, Hugo (Ruiz Pérez) LHCb Collaboration Física de partícules Detectors Quarks Particle physics Detectors Quarks 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 > 20GeV and pseudorapidity 2.2 < η < 4.2. The dependence of the performance on the pT and η of the jet is also measured. 2023-04-18T10:17:03Z 2023-04-18T10:17:03Z 2015-06-22 2023-04-18T10:17:03Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1748-0221 https://hdl.handle.net/2445/196922 658721 eng Reproducció del document publicat a: https://doi.org/10.1088/1748-0221/10/06/P06013 Journal of Instrumentation, 2015, vol. 10, num.
