Effective two-loop potential for SU(2) and SU(3) gluodynamics at a nonzero temperature
The effective potential W(A0) forSU(2) and SU(3) gluodynamics has been calculated by the two-loop method for Τ Φ 0; here A0 is the temporal component of the gauge field. The minimum of W(A0) is reached at A0 ^ 0. At the two-loop level, the SU(2) symmetry is broken to U( 1), and SU(3) is broken to U( ί) X U( 1).
