Description
Hadrons with heavy quarks are promising probes to investigate the detailed
properties of hot and dense medium generated by heavy-ion collisions at
collider energies. Since heavy quarks are sensitive to the transport
properties of the medium, the energy-loss pattern of them is expected to
be quite different from that of light quarks in a strongly-interacting
matter. On the other hand, in order to elicit the actual effects caused by
the hot and dense medium, it is necessary to understand the cold nuclear
matter effect in pA collisions. For example, the pPb data is expected to
provide a baseline for the study of the b-quark energy loss in medium
produced by PbPb collisions. Therefore, the CMS Collaboration at the Large
Hadron Collider (LHC) has analyzed the production cross sections of
$B^{+}$, $B^{0}$, $B^{0}_{s}$ mesons in pPb collisions as a function of
rapidity and the transverse momentum at the nucleon-nucleon center-of-mass
energy of 5.02 TeV . In addition, the nuclear modification factors of the
B mesons have been constructed using the theoretical pp reference spectra
estimated by the perturbative Quantum ChromoDynamics (pQCD) model.
