RT Journal Article T1 Quarkonium: a theory overview A1 González Ferreiro, Elena K1 QCD K1 Heavy-ion theory K1 Phenomenological models AB 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 PB Elsevier SN 0375-9474 YR 2019 FD 2019 LK http://hdl.handle.net/10347/21483 UL http://hdl.handle.net/10347/21483 LA eng NO G.
