Probing the Quark Gluon Plasma with Quarkonia at RHIC

by Dr Rongrong Ma (BNL)


Quarkonia have long been recognized as  unique probes to study the properties of the quark-gluon plasma (QGP) created in high-energy heavy-ion collisions. Specifically, their yields in heavy-ion collisions are expected to be suppressed compared to that in vacuum due to medium-induced dissociation, which is closely related to QGP deconfinement, temperature and dynamics. Furthermore, different quarkonia of different binding energies are predicted to suffer from different levels of suppression, providing an additional handle in studying the medium's properties. In this talk, I will present recent progress in measurements of quarkonium modification in heavy-ion collisions at RHIC, and discuss their physics implications.
