J/Psi and Psi(2S) production in Pb-Pb collisions with the ALICE Muon Spectrometer at the LHC

Abstract

Charmonium states are considered important signatures of the strongly interacting medium created in heavy-ion collisions. In the ALICE experiment, these probes can be investigated in the mu^+mu^- decay channel, in the forward rapidity region (2.5<y<4) down to zero transverse momentum. Results on charmonia production in Pb-Pb collisions at sqrt(s_NN)=2.76 TeV are presented. The centrality and transverse momentum dependence of the inclusive J/Psi nuclear modification factor are shown and compared with theoretical models. Finally, first ALICE results on the Psi(2S) production in Pb-Pb collisions are also discussed.
