abstract
Based on a kinetic description of J/ 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/ 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/) measured by the ALICE Collaboration. We have also made predictions for the RpPb of J/ and the double ratio RpropPb ()/RpropPb(J/) 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/) is slightly smaller than that in the minimum bias collisions, and the double ratio is significantly less than one at backward rapidity. 2013 The Authors.
