Nuclear modification factor of prompt \jpsi as a function of \pt in 0--10\% (upper left panel), 10--30\% (top right panel) and 30--50\% (bottom left panel) centrality classes. Results are compared with similar measurements from the ATLAS and CMS collaborations. The centrality dependent prompt \jpsi \RAA in 1.5 $<$ \pt $<$ 10 \GeVc is shown in the bottom right panel (centrality is expressed in terms of average number of participants). Error bars and boxes represent, respectively, statistical and systematic uncertainties uncorrelated with \pt (centrality, for the bottom right panel). Global uncertainties are shown as boxes around unity.
