摘要：We discuss the calculations of quarkonium spectral functions in potential models and their implications
for the interpretation of the lattice data on quarkonium correlators. In particular, we nd
that melting of different quarkonium states does not lead to signicant change in the Euclidean
time correlators. The large change of the quarkonium correlators above deconnement observed
in the scalar and axial-vector channels appears to be due to the zero mode contribution.
