摘要：

The high-temperature limit of the two-loop effective potential for the Higgs field is calculated from an effective three-dimensional theory, in a general covariant gauge. It is shown explicitly that a gauge-independent result can be extracted for the equation of state from the gauge-dependent effective potential. The convergence of perturbation theory is estimated in the broken phase, utilizing the gauge dependence of the effective potential. © 1995 The American Physical Society.
