Description

J/$\psi$ measurements in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV clearly show a smaller suppression than the one expected from color screening, when compared to binary-scaled pp collisions. The increased yield in Pb$-$Pb collisions can be explained by models that contain a (re)generation component, based on the (re)combination of c$\overline{\rm{c}}$-quarks. Hence, one of the main experimental challenges is to impose strong enough constraints on the production models to shed further light on the behaviour of J/$\psi$ in a hot and dense medium.\\ With unprecedented collision energies during Run 2 of the Large Hadron Collider (LHC) and the unique capabilities of the ALICE detector to study J/$\psi$, new insights on the charmonium production in high-energy Pb$-$Pb collisions can be obtained. The latest results on J/$\psi$ elliptic flow and the inclusive nuclear modification factor as a function of centrality, rapidity and transverse momentum measured in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV with ALICE will be presented.
