Abstract: The inclusive J/psi production in Pb-Pb collisions at the center-of-mass energy per nucleon pair sNN= 5.02 TeV is presented and compared with previous measurements at sNN = 2.76 TeV as a function of the centrality of the collision, and of the J/psi transverse momentum and rapidity. The inclusive J/psi RAA shows a suppression increasing toward higher transverse momentum, with a steeper dependence for central collisions. The modification of the J/psi average transverse momentum and average squared transverse momentum is also studied. Comparisons with the results of models based on a transport equation and on statistical hadronization are carried out.
