Description
Beauty production and phenomena in heavy-ion collisions are considered to be one of the key measurements to address the flavour-dependence of in-medium energy loss in PbPb collisions at the LHC. The CMS experiment has excellent capabilities for measuring b-quark production thanks to the excellent performances of its muon and tracker system, allowing the measurement of $D^{0}$ and J/$\Psi$ mesons from B meson decays, separately from prompt production, as well as fully reconstructed B mesons. In this talk, CMS will present the first measurement of the $v_{2}$ Fourier harmonic and the $R_{AA}$ down to $p_{T} > 3$ GeV/c, for J/$\Psi$ produced in B meson decays, in PbPb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV, as a function of transverse momentum, rapidity and event centrality. New measurements of the $R_{AA}$ of non-prompt J/$\Psi$ and $D^{0}$ from $B$ decay in PbPb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV will also be reported. Finally, the measurement of $R_{AA}$ for fully reconstructed B mesons will be shown, for the first time, in PbPb collisions at 5.02 TeV. The results are compared to various model calculations.
