Centrality and p⊥ dependence of J/ψ suppression in proton-nucleus collisions from parton energy loss

The effects of parton energy loss and p⊥-broadening in cold nuclear matter on the p⊥ and centrality dependence, at various rapidities, of J/ψ suppression in p-A collisions are investigated. Calculations are systematically compared to E866 and PHENIX measurements. The very good agreement between the data and the theoretical expectations further supports p⊥-broadening and the associated medium-induced parton energy loss as dominant effects in J/ψ suppression in high-energy p-A collisions. Predictions for J/ψ (and �) suppression in p-Pb collisions at the LHC are given.
