Abstract

We report on the J/ψ production in Pb-Pb collisions at √s_NN=2.76 TeV recorded with ALICE during the 2010 and 2011 LHC runs. The J/ψ candidates are reconstructed using the e⁺e^- and μ⁺μ^- decay channels at mid- and forward rapidity, respectively. We show the J/ψ nuclear modification factor R_AA as a function of centrality, transverse momentum and rapidity. Our results are compared to the lower energy measurements from PHENIX and to model calculations.
