The High-Temperature Two-Loop Effective Potential of the Electroweak Theory in a General 't Hooft Background Gauge

Abstract

We calculate the high-temperature two-loop effective potential using a general 't~Hooft background gauge. The dependence on the gauge-fixing parameter is investigated. The effective coupling constant at the critical temperature g3(Tc)2 is decreased considerably compared to the one-loop result, independent of .
