Quarkonium Production in p-Pb and Pb-Pb Collisions

Quarkonium production in heavy-ion collisions is one of the key tools to study the Quark-Gluon Plasma, the state of matter which is believed to be formed at the high energy density achieved in heavy-ion collisions. The Large Hadron Collider experiments studied quarkonium production in proton-proton, proton-lead and lead-lead collisions at center-of-mass energies of few TeV. Studying quarkonium production in pp, p–Pb and Pb–Pb collisions allows one to disentangle hot (related to the QGP formation) and cold nuclear matter effects. This article summarizes the recent measurements of quarkonium production by the LHC experiments in p–Pb and Pb–Pb collisions.
