### Description

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, we will present the state of the art of beauty measurements in PbPb collisions in CMS that includes the $R_{AA}$ measurement of fully reconstructed $B^{+}$ mesons and the latest measurements of non-prompt $D^0$ and $J/\psi$ from B decay over a wide transverse momentum range in the same colliding system. The first measurement of the $B_{s}$ $R_{AA}$ in PbPb collisions will also be presented as well as the ratio between the production yield of $B_{s}$ and $B^{+}$.
