Description
Beauty quarks are considered to be one of the golden probes of the strong interacting medium created in heavy-ion collisions as they are mainly produced via initial hard scatterings and strongly interact with the medium. They are sensitive to the transport properties of the medium and may interact with the QCD matter differently from light quarks. High-precision measurement of B mesons will shed light on our knowledge of flavour-dependence of in-medium energy loss. In addition, the measurements of the production of strange and non-strange beauty mesons provides fundamental insights into relevance of mechanisms of beauty recombination in the quark-gluon plasma. Using the large statistics PbPb data collected in 2018, measurements of $B_{S}^{0}$ and $B^{+}$ have been performed with the CMS detector. In this talk, we will present the ratio of production yield between $B_{S}^{0}$ and $B^{+}$ in PbPb collisions with full hadronic reconstruction. The result will be compared with the same observable measured in pp collisions and we will also discuss the comparison with several theoretical predictions. We will also present the latest measurements of production of fully reconstructed $B^{+}$ and non-prompt $D^{0}$ and $J/\psi$ from b decay in PbPb collisions at 5.02 TeV.
