Abstract
We study charmoinum correlators and spectral functions at finite temperature within the quenched approximation using isotropic lattices with lattice spacing a(-1) = 4.86 GeV and 9.72 GeV. Although we observe some medium modifications of the ground state charmonium spectral function above deconfinement, we find that ground state charmonia (J/psi and eta(c)) exist in the deconfined phase at least up to temperatures as high as 1.5T(c). P-wave charmonia (X) on the other hand are dissociated already at 1.12T(c).
