dc.description.abstractThe production cross sections of B0smesons and charge conjugates are measured in proton-proton (pp) and PbPb collisions via the exclusive decay channel B0s?J/????+??K+K?at a center-of-mass energy of 5.02TeV per nucleon pair and within the rapidity range |y| <2.4using the CMS detector at the LHC. The pp measurement is performed as a function of transverse momentum (pT) of the B0smesons in the range of 7 to 50GeV/cand is compared to the predictions of perturbative QCD calculations. The B0sproduction yield in PbPb collisions is measured in two pTintervals, 7 to 15 and 15 to 50GeV/c, and compared to the yield in pp collisions in the same kinematic region. The nuclear modification factor (RAA) is found to be 1.5 ±0.6(stat) ±0.5(syst)for 7–15GeV/c, and 0.87 ±0.30(stat) ±0.17(syst)for 15–50GeV/c, respectively. Within current uncertainties, the B0sresults are consistent with models of strangeness enhancement, and suppression by parton energy loss, as observed for the B+mesonsen_US
