Abstract / Bemerkung
The recently observed gauge-fixing dependence in covariant gauges of the damping rates of the quantum chromodynamics (QCD) gluonic and fermionic excitations at high temperatures and long wavelengths is reviewed. The analysis is based on the method by Braaten and Pisarski for resumming hard thermal loops using the Ward identities satisfied by the effective propagators and vertex functions. A proposed resolution of the gauge problem by regularizing the mass singularities is also discussed.
