Abstract
Based on a kinetic description of J/ψ dissociation and production in an expanding quark–gluon plasma that is described by a 2+1 dimensional ideal hydrodynamics, we have studied the hot medium effects on J/ψ production in p+Pb collisions at sNN=5.02 TeV. Including also the cold nuclear matter effects, we are able to reproduce recent experimental results on the nuclear modification factor RpPb(J/ψ) measured by the ALICE Collaboration. We have also made predictions for the RpPb of J/ψ and the double ratio RpPbpro(ψ′)/RpPbpro(J/ψ) of prompt quarkonia produced in the most central 10% p+Pb collisions. We find that different from the cold nuclear matter effects, the RpPb(J/ψ) is slightly smaller than that in the minimum bias collisions, and the double ratio is significantly less than one at backward rapidity.
