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

J. Kripfganz · A. Laser · M.G. Schmidt

Abstract

We calculate the high-temperature two-loop effective potential using a general 't~Hooft background gauge. The dependence on the gauge-fixing parameter $ξ$ is investigated. The effective coupling constant at the critical temperature $g_{3} (T_{c})^{2}$ is decreased considerably compared to the one-loop result, independent of $ξ$ .
