Description

At high temperature, Lattice Quantum Chromodynamics (LQCD) predicts the existence of dense and hot nuclear matter which behaves as a deconfined medium of quarks and gluons. Inside such medium, quarkonia are suppressed due to the color-screeening effect. However, at LHC energies an enhancement in the production of $J/\psi$ has been observed. This enhancement effect is more prominent at lower dimuon transverse momentum ($p_{T}$ $<$ 4 GeV/c) and central Pb-Pb collisions.

In the present study, the $J/\psi$ production as measured by ALICE in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV, in the forward rapidity region (2.5 $<$ y $<$ 4.0), is discussed. The $J/\psi$ nuclear modification factor $R_{AA}$ has been measured as a function of rapidity in different $p_{T}$ bins (0 - 2 GeV/c, 2 - 4 GeV/c, 4 - 6 GeV/c and $>$ 6 GeV/c) and centrality bins (0 - 20 $\%$, 20 - 40 $\%$ and $>$ 40 $\%$). The study of the $R_{AA}$ as a function of rapidity and transverse momentum may provide a deeper insight on the mechanism of $J/\psi$ regeneration and suppression.

New ALICE results on the $J/\psi$ nuclear modification factor measured as a function of rapidity, in $p_{T}$ and centrality classes, in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV will be presented.
