Quarkonium production in p–Pb collisions with ALICE

Abstract

The production of quarkonia, bound states of quark and anti-quark pairs, is intensively studied both experimentally and theoretically. They are ideal probes of the Quark-Gluon Plasma (QGP) formed in heavy-ion collisions. At the beginning of 2013, data from p–Pb collisions at sNN=5.02 TeV have been collected by ALICE, which can be exploited to measure cold nuclear matter (CNM) effects on quarkonium production. These measurements are important in order to disentangle, in Pb–Pb collisions, hot and CNM effects. In this paper final ALICE results on the charmonium and bottomonium production in p–Pb collisions from Run I of the LHC are presented. ALICE measurements are compared to various models of CNM effects and to PHENIX measurements.
