| Abstract: The identification of jets originating from b quarks is an important component in analyses searching for new physics and for measurements of standard model processes. Particularly challenging are those involving top-quark or Higgs-boson production with decays in the boosted regime. Studies of b-quark jet algorithms and their performances are presented, using multijet events and $ \mathrm{t \bar{t} } $ events recorded in proton-proton collision data at $ \sqrt{s}= $ 8 TeV with the CMS detector in the year 2012. The b-tagging efficiency and misidentification probability are determined in data and in simulation over a wide range of jet transverse momenta from 20 GeV/$c$ to more than 800 GeV/$c$. For the first time in CMS, dedicated studies of b-quark identification in boosted topologies are presented. | ||
