摘要：

We calculate the high-temperature two-loop effective potential using a general 't Hooft background gauge. The dependence on the gauge-fixing parameter xi 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 xi.
