Measurement of the B± Meson Nuclear Modification Factor in Pb-Pb Collisions at √{sN N }=5.02 TeV
The differential production cross sections of B± mesons are measured via the exclusive decay channels B±→J /ψ K±→μ+μ-K± as a function of transverse momentum in p p and Pb-Pb collisions at a center-of-mass energy √{sN N }=5.02 TeV per nucleon pair with the CMS detector at the LHC. The p p (Pb-Pb ) data set used for this analysis corresponds to an
