Abstract Finite temperature lattice QCD indicates that the charmonium ground state J / ψ can survive in a quark–gluon plasma up to 1.5 T c or more, while the excited states χ c and ψ ′ are dissociated just above T c . We assume that the χ c suffers the same form of suppression as that observed for the ψ ′ in SPS experiments, and that the directly produced J / ψ is unaffected at presently available energy densities. This provides a parameter-free description of J / ψ and ψ ′ suppression which… Expand

Analyzing correlation functions of charmonia at finite temperature (T) on 32(3)x(32-96) anisotropic lattices by the maximum entropy method (MEM) finds that J/psi and eta(c) survive as distinct resonances in the plasma even up to T approximately 1.6T(c), which suggests that the deconfined plasma is nonperturbative enough to hold heavy-quark bound states.
