Abstract (data abstract)
CERN-LHC-ALICE. The inclusive J/$\psi$ production in Pb-Pb collisions at the center-of-mass energy per nucleon pair $\sqrt{s_{\rm NN}}$ = 5.02 TeV, measured with the ALICE detector at the CERN LHC, is reported. The J/$\psi$ meson is reconstructed via the dimuon decay channel at forward rapidity ($2.5<y<4$) down to zero transverse momentum. The suppression of the J/$\psi$ yield in Pb-Pb collisions with respect to binary-scaled pp collisions is quantified by the nuclear modification factor ($R_{\rm AA}$). The $R_{\rm AA}$ at $\sqrt{s_{\rm NN}}$ = 5.02 TeV is presented and compared with previous measurements at $\sqrt{s_{\rm NN}}$ = 2.76 TeV as a function of the centrality of the collision, and of the J/$\psi$ transverse momentum and rapidity. The inclusive J/$\psi$ $R_{\rm AA}$ shows a suppression increasing toward higher $p_{\rm T}$, with a steeper dependence for central collisions. The modification of the J/$\psi$ average $p_{\rm T}$ and $p_{\rm T}^2$ is also studied. Comparisons with the results of models based on a transport equation and on statistical hadronization are also carried out.
