ABSTRACT We report first results for spectral functions of charmonium in 2-flavour
QCD. The spectral functions are determined from vector and pseudoscalar
correlators on a dynamical, anisotropic lattice. J/psi and eta_c are found to
survive well into the deconfined phase before melting away at T<~2T_c. Current
systematic uncertainties prevent us from drawing any definite conclusions at
this stage.

    ABSTRACT: We compute charmonium spectral functions in 2-flavour QCD using the maximum entropy method and anisotropic lattices. We find that the S-waves (J/ψ and ηc) survive up to temperatures close to 2Tc, while the P-waves (χc0 and χc1) melt away below 1.3Tc.

    ABSTRACT: Charmonium systems in two-flavour QCD at non-zero temperature are studied at, and above the deconfining transition. Using anisotropic lattices the MEM approach is used to extract spectral functions for these channels. By carefully varying some of the irrelevant parameters in the MEM procedure, we confirm that our systematic effects are under control. The eta_c and J/psi states are found to persist at temperatures >~ 1.3 T_c in agreement with our previous dynamical studies.

    ABSTRACT: We extract the $Q$-$\bar Q$ potential by using the thermodynamic quantities obtained in lattice gauge calculations. The potential is tested and found to give dissociation temperatures that agree well with those from lattice gauge spectral function analysis. Using such a $Q$-$\bar Q$ potential, we examine the quarkonium states in a quark-gluon plasma and determine the `quark drip lines' which separate the region of bound color-singlet $Q\bar Q$ states from the unbound region. The characteristics of the quark drip lines severely limit the region of possible bound $Q\bar Q$ states with light quarks to temperatures close to the phase transition temperature. Bound quarkonia with light quarks may exist very near the phase transition temperature if their effective quark mass is of the order of 300-400 MeV and higher.
