Description
Assuming full screening of quarkonia in QGP as well as full thermalization of charm quarks in QGP, quarkonium production in the Statistical Hadronization Model occurs at chemical freeze-out (which, for high energies, likely coincides with the QCD phase boundary). The model describes very well the LHC J/psi data on centrality, transverse momentum and rapidity dependence and gives definite predictions for psi(2S) production.
Whether the same generation mechanism applies for the bottomonium is not incontroversial, but remains a tantalizing possibility, which will be presented as well.
