Basic Features

Quarkonium production has been considered as a tool to study the medium formed in high-energy nuclear collisions, assuming that the formation of a hot and dense environment modifies the production pattern observed in elementary collisions. The basic features measured there are the relative fractions of hidden to open heavy flavor and the relative fractions of the different hidden heavy flavor states. Hence the essential question is if and how these quantities are modified in nuclear collisions. We show how the relevant data must be calibrated; that is, what reference has to be used, in order to determine this in a model-independent way.

We first review the cold and hot nuclear matter effects on quarkonium production in high energy collisions, then discuss three kinds of models to describe the quarkonium suppression and regeneration: the sequential dissociation, the statistical production and the transport approach, and finally make comparisons between the models and the experimental data from heavy ion collisions at SPS, RHIC and LHC energies.

Nuclear Collisions

According to the usual application of the sequential-suppression picture to the dynamics of heavy quarkonia in the hot medium formed in ultrarelativistic nuclear collisions, quark–antiquark pairs created in a given bound or unbound state remain in that same state as the medium evolves. We argue that this scenario implicitly assumes an adiabatic evolution of the quarkonia and we show that the validity of the adiabaticity assumption is questionable.
