$B_s$ and $B^+$ meson nuclear modification factors in PbPb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV with the CMS detector

Beauty quark production in heavy-ion collisions is considered to be one of the key measurements to address the flavour-dependence of in-medium energy loss in heavy-ion collisions. On the other hand, the measurement of the production of strange beauty mesons can provide fundamental insights into the relevance of mechanisms of beauty recombination in the quark-gluon plasma. In this talk, CMS will present the nuclear modification factor, $R_{AA}$, of fully reconstructed $B_{s}$ and $B^{+}$ mesons as a function of transverse momentum at $\sqrt{s_{NN}}=5.02$ = 5.02 TeV in PbPb collisions for the first time. The $R_{AA}$ double ratio between $B_{s}$ and $B^{+}$ is also presented.
