| description | The differential production cross sections of B� mesons are measured via the exclusive decay channels
B� → J=ψK� → μþμ−K� as a function of transverse momentum in pp and Pb-Pb collisions at a centerof-mass
energy ffiffiffiffiffiffiffiffi
sNN p ¼ 5.02 TeV per nucleon pair with the CMS detector at the LHC. The ppðPb PbÞ
data set used for this analysis corresponds to an integrated luminosity of 28.0 pb−1 (351 μb−1). The
measurement is performed in the B� meson transverse momentum range of 7 to 50 GeV=c, in the rapidity
interval jyj < 2.4. In this kinematic range, a strong suppression of the production cross section by about a
factor of 2 is observed in the Pb-Pb system in comparison to the expectation from pp reference data. These
results are found to be roughly compatible with theoretical calculations incorporating beauty quark
diffusion and energy loss in a quark-gluon plasma. |
