Abstract: 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 $| {y} | < $ 2.4, extending down to $p_{\mathrm{T}}= $ 3 GeV/$c$ in the 1.6 $ < |{y}| < $ 2.4 range. The ${v_{2}} $ of prompt $\mathrm{J}/\psi$ is found to be nonzero and constant over the full kinematic range studied, while the measured ${v_{2}} $ of nonprompt $\mathrm{J}/\psi$ is consistent with zero. The ${R_{\mathrm{AA}}} $of prompt $\mathrm{J}/\psi$ exhibits a suppression that increases with centrality but does not vary as a function of either $y$ or $p_{\mathrm{T}}$ in the fiducial range. The nonprompt $\mathrm{J}/\psi$ $ {R_{\mathrm{AA}}} $ shows a suppression which becomes stronger as rapidity or $ p_{\mathrm{T}}$ increase. The ${v_{2}} $ and nuclear suppression of open and hidden charm, and of open charm and beauty, are compared. | ||

Summary |
The production of prompt and nonprompt (coming from b hadron decay) $ \mathrm{J}/\psi $ has been studied in pp and PbPb collisions at $\sqrt{s_{\mathrm{NN}}} = $ 2.76 TeV. The $ {R_{\mathrm{AA}}} $ of the prompt $ \mathrm{J}/\psi $ mesons, integrated over the rapidity range $ | {y} | < $ 2.4 and high $ p_{\mathrm{T}} $, 6.5 $ < p_{\mathrm{T}} < $ 30 GeV/$c$, is measured in 12 centrality bins. The $ {R_{\mathrm{AA}}} $ is less than unity even in the most peripheral bin, and the suppression becomes steadily stronger as centrality increases. Integrated over rapidity ($ p_{\mathrm{T}} $) and centrality, no strong evidence for a $ p_{\mathrm{T}} $ (rapidity) dependence of the suppression is found. The azimuthal anisotropy of prompt $ \mathrm{J}/\psi $ mesons shows a nonzero ${v_{2}} $ value in all studied bins, while no strong dependence on centrality, rapidity, or $ p_{\mathrm{T}} $ is observed. The $ {R_{\mathrm{AA}}} $ of nonprompt $ \mathrm{J}/\psi $ mesons shows a slow decrease with increasing centrality and rapidity. The results show less suppression at low $ p_{\mathrm{T}} $. The first measurement of the nonprompt $ \mathrm{J}/\psi $ ${v_{2}} $ is also reported in two $ p_{\mathrm{T}} $ bins for 10-60% event centrality, and the values are consistent with zero elliptical azimuthal anisotropy, though both nominal values are positive. |
