Abstract

We calculate the bound state properties of J/ψJ/\psi in a hot and dense QCD plasma using phenomenological potentials augmented by inputs from perturbative QCD. The temperature and density region of study will be relevant in future heavy ion collision experiments at FAIR. We find that the effect of baryon density on the dissociation of J/ψJ/\psi is small in this regime. However we indicate that if there is a critical end point in the QCD phase diagram then strong density fluctuation will dissociate charmonia near hadronization. The measurement of J/ψJ/\psi suppression can therefore signify the existence of the critical point unambiguously.
