摘要：

The thermal widths for heavy quarkonia are calculated for both Coulomb gauge(CG) and Feynman gauge(FG),and the comparisons between these results with the hard thermal loop(HTL) approximation ones are illustrated.The dissociation temperatures of heavy quarkonia in thermal medium are also discussed for CG,FG and HTL cases.It is shown that the thermal widths,derived from the HTL approximation and used in many research studies,cause some errors in the practical calculations at the temperature range accessible in the present experiment,and the problem of gauge dependence cannot be avoided when the complete self energy is used in the derivation of potential.
