  "abstract": "<p>The inclusive J/\u03c8 nuclear modification factor ( RAA ) in Pb\u2013Pb collisions at sNN=2.76\u00a0TeV has been measured by ALICE as a function of centrality in the e+e\u2212 decay channel at mid-rapidity ( |y|&lt;0.8 ) and as a function of centrality, transverse momentum and rapidity in the \u03bc+\u03bc\u2212 decay channel at forward-rapidity ( 2.5&lt;y&lt;4 ). The J/\u03c8 yields measured in Pb\u2013Pb 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\u2013Pb cross section is 0.72\u00b10.06(stat.)\u00b10.10(syst.) at mid-rapidity and 0.58\u00b10.01(stat.)\u00b10.09(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/\u03c8 yield originates from charm quark (re)combination in the deconfined partonic medium.</p>",
