Description
The inclusive J/ψ nuclear modification factor (R AA) in Pb–Pb collisions at s NN= 2.76 TeV has been measured by ALICE as a function of centrality in the e+ e− decay channel at mid-rapidity (| y|< 0.8) and as a function of centrality, transverse momentum and rapidity in the μ+ μ− decay channel at forward-rapidity (2.5< y< 4). The J/ψ yields measured in Pb–Pb are suppressed compared to those in pp collisions scaled by the number of binary collisions. The R AA integrated over a centrality range corresponding to 90% of the inelastic Pb–Pb cross section is 0.72±0.06 (stat.)±0.10 (syst.) at mid-rapidity and 0.58±0.01 (stat.)±0.09 (syst.) at forward-rapidity. At low transverse momentum, significantly larger values of R AA are measured at forward-rapidity compared to measurements at lower energy. These features suggest that a contribution to the J/ψ yield originates from charm quark (re) combination in the deconfined …
