Quarkonium: a theory overview

Understand

Quarkonium has long been proposed as one of the golden probes to identify the phase transition from confined hadronic matter to the deconfined quark-gluon plasma in heavy-ion collisions.

• Since then, we have achieved a better understanding, not only about the propagation of quarkonium in-medium, but also about its production.
• Recent theoretical developments in our comprehension of the quarkonium production mechanism in proton-proton collisions and on the propagation of quarkonia in proton-nucleus and nucleus-nucleus collisions are reviewed and discussed.
