摘要：

A two-loop calculation of the free energy for finite temperature SU(3) gauge theory in an external field A0=const is carried out using background Feynman gauge. Nontrivial minima of the free energy are obtained at A0{gT for g→0 corresponding to the gauge symmetry breaking SU(3)→U(1)×U(1). Higher order perturbative effects are briefly discussed. © 1990 Springer-Verlag.
