Description
The ALICE Experiment at the Large Hadron Collider (LHC) provides excellent capabilities to study charmonium production at low transverse momentum ($p_\mathrm{T}$). At central ($|y|<0.9$) and forward rapidity ($2.5<y<4$), J$/\psi$ are reconstructed via their leptonic decay channels down to $p_\mathrm{T}$ = 0. We will present ALICE results on the inclusive J$/\psi$ nuclear modification factor $R_\mathrm{AA}$ as a function of collision centrality, rapidity and p_\mathrm{T}, as well as results on the J$/\psi$ $\langle p_\mathrm{T} \rangle$ in Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}=2.76$ TeV. At mid-rapidity, we will also report the separation of prompt and non-prompt J$/\psi$ down to p_\mathrm{T}=1.3 GeV/$c$. The measurements provide, in combination with results from lower energies and theoretical predictions, detailed information on the different mechanisms related to the presence of the hot medium produced in heavy-ion collisions.
