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

Charmonium dissociation temperatures in lattice QCD with a finite volume technique
Dissociation temperatures of J/ψ, ψ' and Χ c states play key roles in the sequential J/ψ suppression scenario for high-energy heavy-ion collisions. We report on a study of charmonium dissociationExpand
Charmonium properties in the quark-gluon plasma

A quantitative analysis of charmonium suppression in nuclear collisions
Data from J/ψ and ψ′ production in p - A collisions are used to determine the cross section for absorption of pre-resonance charmonium in nuclear matter. The J/ψ suppression in O - Cu, O - U and S -Expand

About 40-50% of the quarkonium ground states J/psi (1S) and Y(1S) produced in hadronic collisions originate from the decay of higher excitations. In a hot medium, these higher states are dissociatedExpand

J/psi and eta(c) in the deconfined plasma from lattice QCD.
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.
