Abstract: In this study we apply the Remler formalism to charmonium production at Super Proton Synchrotron (SPS) and GSI/Facility for Antiproton and Ion Research (FAIR) energies in order to investigate the effects of baryon-rich matter on charmonium production and dissociation in heavy-ion collisions within the parton-hadron-string dynamics. As a first step the Remler formalism is tested in p + p collisions and then applied to p + A collisions in order to extract the nuclear absorption cross section of charmonium, which is then utilized in heavy-ion collisions. We find that the Remler formalism successfully describes charmonium production in heavy-ion collisions at SPS energies when an in-medium heavy quark potential is implemented, in which J / ψ dissociates near T c . Finally, the same formalism is applied to the low CERN/SPS energy and GSI/FAIR energies, where we estimate charmonium production.
