Suppression and Azimuthal Anisotropy of Prompt and Nonprompt $J/\psi$ Production in PbPb Collisions at $\sqrt{s_{NN}}$
The nuclear modification factor ${R_{\mathrm{AA}}} $ and the azimuthal anisotropy coefficient ${v_{2}} $ of prompt and nonprompt (i.e. those from decays of b hadrons) $\mathrm{J}/\psi$ mesons, measured from PbPb and pp collisions at $\sqrt{s_{\mathrm{NN}}} = $ 2.76 TeV at the LHC, are reported. The results are presented in several event centrality intervals and several kinematic regions, for transverse momenta $p_{\mathrm{T}}> $ 6.5 GeV/$c$ and rapidity $
Suppression of Non-prompt J/psi, Prompt J/psi, and Y(1S) in PbPb Collisions at Sqrt(sNN)
Yields of prompt and non-prompt J/psi, as well as Y(1S) mesons, are measured by the CMS experiment via their dimuon decays in PbPb and pp collisions at sqrt(sNN) = 2.76 TeV for quarkonium rapidity.
Measurement of Prompt and Nonprompt J/psi Production in Pp and PPb Collisions at Sqrt(s[NN]
This paper reports the measurement of J/psi meson production in proton-proton (pp) and proton-lead (pPb) collisions at a center-of-mass energy per nucleon pair of 5.02 TeV by the CMS experiment at the LHC. The data samples used in the analysis correspond to integrated luminosities of 28 inverse picobarns and 35 inverse nanobarns for pp and pPb collisions, respectively. Prompt and nonprompt J/psi mesons, the latter issuing from the decay of B mesons, are measured in their dimuon decay channels. Differential cross sections are measured in the transverse momentum range of 2
