| Özet |
| The B s 0 and B+ production yields are measured in PbPb collisions at a center-of-mass energy per nucleon pair of 5.02 TeV. The data sample, collected with the CMS detector at the LHC, corresponds to an integrated luminosity of 1.7 nb− 1. The mesons are reconstructed in the exclusive decay channels B→ s 0 J/ψ (μ+ μ−) ϕ (K+ K−) and B→+ J/ψ (μ+ μ−) K+, in the transverse momentum range 7–50 GeV/c and absolute rapidity 0–2.4. The B s 0 meson is observed with a statistical significance in excess of five standard deviations for the first time in nucleus-nucleus collisions. The measurements are performed as functions of the transverse momentum of the B mesons and of the PbPb collision centrality. The ratio of production yields of B s 0 and B+ is measured and compared to theoretical models that include quark recombination effects. |
