J/psi suppression in p-A collisions from parton energy loss in cold QCD matter
F. Arleo1, S. Peigné2

The effects of energy loss in cold nuclear matter on J/psi 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/psi suppression data at large xF 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/psi and Upsilon suppression in p-Pb collisions at the LHC are made.
