Theoretical overview on (hidden) charm in high-energy heavy-ion collisions

Abstract

Recent developments in the theoretical evaluation of charmonium production in ultrarelativistic heavy-ion collisions (URHICs) are discussed. In particular, the consequences of equilibrium properties of open and hidden charm states—accessible, e.g., in QCD lattice gauge calculations—are assessed. These include abundances as well as formation and dissociation rates of charmonia in both hadronic and quark–gluon matter.
