| dc.description.abstract | We present a measurement of b jet transverse momentum (\(p_T\)) spectra in proton-lead (pPb) collisions using a dataset corresponding to about 35 nb\(^{-1}\) collected with the CMS detector at the LHC. 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 nucleonânucleon 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 \(p_T\) between 55 and 400 GeV/c and with |\(\eta_{lab}\)| < 2. We also compare this result to predictions from models using perturbative calculations in quantum chromodynamics. | en_US |
