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.
