ALICE at the LHC provides unique capabilities to study charmonium production at low transverse momenta (PT). At central rapidity, (vertical bar y vertical bar < 0.8), ALICE can reconstruct J/psi via their decay into two electrons down to zero p(T). Results at mid-rapidity on the inclusive J/psi nuclear modification factor R-AA as a function of centrality in Pb-Pb collisions at root s(NN) = 5.02 TeV and comparisons to lower energies and models are shown. In addition, the yield of the J/psi produced with very low p(T). in the most peripheral collisions and the J/psi elliptic flow (nu(2)) are also presented.
