Charmonium production at energies available at the CERN Super Proton Synchrotron and Facility for Antiproton and Ion Research
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.
