Measurement of B-s(0) meson production in pp and PbPb collisions at root S-NN=5.02 TeV
The production cross sections of B0 s mesons and charge conjugates are measured in proton-proton (pp) and PbPb collisions via the exclusive decay channel B0 s → J/ψφ → μ+μ−K+K− at a center-of-mass energy of 5.02 TeV per nucleon pair and within the rapidity range |y| < 2.4 using the CMS detect...

| description | The production cross sections of B0
s mesons and charge conjugates are measured in proton-proton (pp)
and PbPb collisions via the exclusive decay channel B0
s → J/ψφ → μ+μ−K+K− at a center-of-mass
energy of 5.02 TeV per nucleon pair and within the rapidity range |y| < 2.4 using the CMS detector at
the LHC. The pp measurement is performed as a function of transverse momentum (pT) of the B0
s mesons
in the range of 7 to 50 GeV/c and is compared to the predictions of perturbative QCD calculations. The
B0
s production yield in PbPb collisions is measured in two pT intervals, 7 to 15 and 15 to 50 GeV/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 7–15 GeV/c, and 0.87 ± 0.30(stat) ± 0.17(syst) for
15–50 GeV/c, respectively. Within current uncertainties, the B0
s results are consistent with models of
strangeness enhancement, and suppression by parton energy loss, as observed for the B+ mesons. |
