Measurements of strange and non strange beauty production in PbPb collisions at 5.02 TeV with the CMS detector

Production yields of strange and non strange beauty particles are measured by the CMS collaboration in proton-proton and PbPb collisions at 5.02 TeV. Consistent suppression of $B^{+}$, nonprompt $J/\psi$ (coming from decays of b hadrons) and nonprompt $D^0$ is observed in PbPb collisions compared to...

description Production yields of strange and non strange beauty particles are measured by the CMS collaboration in proton-proton and PbPb collisions at 5.02 TeV. Consistent suppression of $B^{+}$, nonprompt $J/\psi$ (coming from decays of b hadrons) and nonprompt $D^0$ is observed in PbPb collisions compared to proton-proton collisions. Beauty particles seem to be less suppressed than charm and light flavor particles at transverse momentum around 10 GeV/c, which is in line with expectation from mass ordering of parton energy loss. We also report the first measurement of $B_{s}^{0}$ yield in heavy ion collisions. There is an indication of less suppression of $B_{s}^{0}$ comparing to $B^{+}$, which is consistent with the strangeness enhancement in quark-gluon plasma and the recombination production mechanism of $B_{s}^{0}$.
