Jets from b quark fragmentation are found by exploiting the long lifetime of hadrons containing a b quark through tagging methods using distributions of the secondary vertex mass and displacement. Extracted cross sections for b jets are scaled by the effective number of nucleon–nucleon collisions and are compared to a reference obtained from PYTHIA simulations of pp collisions. The PYTHIA-based estimate of the nuclear modification factor is found to be 1.22±0.15(stat+syst pPb)±0.27(syst PYTHIA) averaged over all jets with pT between 55 and 400 GeV/c and with |ηlab|<2. We also compare this result to predictions from models using perturbative calculations in quantum chromodynamics. © 2016 CERN for the benefit of the CMS CollaborationElsevier B.V.2016Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/15263https://doi.org/10.1016/j.physletb.2016.01.0100370-2693enPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physicsinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/15263
