Charmonium production in Pb-Pb collisions at $\sqrt{{s}_{{\rm{N}}{\rm{N}}}}=2.76\,{\rm{TeV}}$ and $\sqrt{{s}_{{\rm{N}}{\rm{N}}}}=5.02\,{\rm{TeV}}$ measured with ALICE at the LHC

We report on the results of the charmonium production in Pb-Pb collisions at $\sqrt{{s}_{{\rm{NN}}}}=2.76$ and 5.02 TeV measured with the ALICE detector at the LHC. In particular, we focus on the new measurements obtained at $\sqrt{{s}_{{\rm{N}}{\rm{N}}}}=5.02\,{\rm{TeV}}$ for the J/ψ at forward rapidity in the dimuon decay channel and their comparison with previous measurements at lower energy and model calculations.
