Abstract

A comprehensive parameterization of the colour singlet heavy quark free energy above $T_c$ is given, using the lattice data in quenched ( $N_f=0$ ) and unquenched ( $N_f=2$ and $N_f=3$ ) QCD. The corresponding (temperature dependent) potentials thus obtained are then inserted into the Schr\"odinger equation for the charmonium and the bottomonium in the deconfined phase of QCD. The solution of the equation provides an estimate of the melting temperature and of the radii for the different $c\bar{c}$ and $b\bar{b}$ bound states.
