| 英文摘要 | The nuclear modification factor r-aa and the azimuthal anisotropy coefficient v(2) ofprompt and nonprompt (i.e. those from decays of b hadrons) j/psi mesons, measured from pbpb and pp collisions at root s-nn = 2.76 rfev at ithelhc, are reported. the results are presented in several event centrality intervals and several kinematic regions, for transverse momenta p(t) > 6.5 gev/c and rapidity vertical bar y vertical bar < 2.4, extending down to p(t) = 3 gev/c in the 1.6 < vertical bar y vertical bar < 2.4 range. the v(2) of prompt j/psi is found to be nonzero, but with no strong dependence on centrality, rapidity, or p(t) over the full kinematic range studied. the measured v(2) of nonprompt j/psi is consistent with zero. the r-aa of prompt j/psi exhibits a suppression that increases from peripheral to central collisions but does not vary strongly as a function of either y or pt in the fiducial range. the nonprompt j/psi raa shows a suppression which becomes stronger as rapidity or p(t) increases. the v(2) and r-aa of open and hidden charm, and of open charm and beauty, are compared. |
