【 摘 要 】

The production of charmonium states, J/ψ and ψ(2S), in heavy-ion collisions, is an important probe to investigate the formation of a plasma of quarks and gluons. In such a hot and deconfined medium, quarkonium production is, indeed, expected to be significantly modified, with respect to the pp yields, due to the interplay of color screening and charm-quark recombination mechanisms. The ALICE Collaboration at the LHC has measured charmonium production in Pb-Pb collisions at √sNN. The nuclear modification factor of inclusive J/ψ, evaluated at forward (2.5
