Contribution

It extends the statistical hadronization model to include predictions for charm production at LHC and FAIR energies, highlighting potential differences in charmonium yields.

Findings

Model reproduces RHIC data accurately.

Predicts significant changes in charmonium production at LHC.

Extends predictions to charm production near threshold energies.

Abstract

We discuss the production of charmonium in nuclear collisions within the framework of the statistical hadronization model. We demonstrate that the model reproduces very well the availble data at RHIC. We provide predictions for the LHC energy where, dependently on the charm production cross section, a dramatically different behaviour of charmonium production as a function of centrality might be expected. We extend our predictions for charm production towards the threshold energies, where charm is expected to be measured at the future FAIR facility.
