Description
Quarkonia measurements in heavy ion collisions are ideal probes of the Quark-Gluon Plasma (QGP). Their production will be suppressed due to static and dynamical dissociation in the hot and dense medium, which has been suggested as a signature of the formation of the QGP. Besides the dissociation effects, there are other mechanisms, such as the regeneration effect and the cold nuclear effects, which could affect the their yields in heavy-ion collisions.
In this talk, we will present recent measurements of quarkonium production and suppression at RHIC, including collision energy and system size dependence of quarkonia yield in heavy-ion collisions, sequential suppression of quarkonia at RHIC, J/$\psi$ polarization and spin alignment in heavy-ion collisions, as well as J/$\psi$ energy correlator and photon-induced production at RHIC. Physics implications of these results will also be discussed.
