| Özet |
| Yields of prompt and non-prompt J/ψ, as well as(1S) mesons, are measured by the CMS experiment via their μ+ μ− decays in PbPb and pp collisions at TeV for quarkonium rapidity| y|< 2.4. Differential cross sections and nuclear modification factors are reported as functions of y and transverse momentum p T, as well as collision centrality. For prompt J/ψ with relatively high p T (6.5< p T< 30 GeV/c), a strong, centrality-dependent suppression is observed in PbPb collisions, compared to the yield in pp collisions scaled by the number of inelastic nucleon-nucleon collisions. In the same kinematic range, a suppression of non-prompt J/ψ, which is sensitive to the in-medium b-quark energy loss, is measured for the first time. Also the low-p T(1S) mesons are suppressed in PbPb collisions. |
