Centrality, rapidity and transverse momentum dependence of J/ [psi] suppression in Pb-Pb collisions at √sNN=2.76 TeV
The inclusive J/ψ nuclear modification factor (RAA) in Pb-Pb collisions at sNN=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...

| 520 | |a The inclusive J/ψ nuclear modification factor (RAA) in Pb-Pb collisions at sNN=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 RAA 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 RAA 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 partonic medium. | ||
