Meson spectral functions above deconfinement

I am goint to present lattice calculations of meson spectral functions above
the critical temperature in quenched QCD both for heavy and light quarks. We
find the ground state charmonia exist up to 2.25T_c while the excited P-wave
charmonia dissolve at 1.1T_c (T_c is the critical temperature). For
bottomonia excited P-state may survive till 2.25T_c while 1S state will
survive till T>3T_c. It is found that also in the case of the light quarks
meson spectral function indicate strong correlation between quark and
anti-quark.
