Notlar	BMBWF and FWF (Austria); FNRS the determination of the uncertainties related to data/MC comparisons, an identical procedure to that used for the production yield is employed, but utilizing only tracking related variables, using the B+ channel. The dominant uncertainty arises from data/MC agreement and the limited MC sample size. The Rratio results are shown in Fig. 3as functions of the mesons' pT(upper) and event centrality (lower).
Örnek Metin	The Bs 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→s0J/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 Bs 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 Bs 0 and B+ is measured and compared to theoretical models that include quark recombination effects.
