title: J/ψ suppression in p-A collisions from parton energy loss in cold QCD matter.
abstract: The effects of energy loss in cold nuclear matter on J/ψ suppression in p-A collisions are studied. A simple model based on first principles and depending on a single free parameter is able to reproduce J/ψ suppression data at large x(F) and at various center-of-mass energies. These results strongly support energy loss as a dominant effect in quarkonium suppression. They also give some hint on its hadroproduction mechanism suggesting color neutralization to happen on long time scales. Predictions for J/ψ and Υ suppression in p-Pb collisions at the LHC are made.
