Abstract: (Elsevier)
For any renormalize field theory in four dimensions we obtain the two-loop counterterms for the gauge coupling and the scalar potential, using the background-field method. The calculation was performed in two different subtraction schemes: one is the ordinary dimensional regularization, the other is the so-called dimensional reduction scheme. We show that already at the two-loop level differences occur for the scalar coupling-constants. Only dimensional reduction preserves supersymmetry up to this level.- FIELD THEORETICAL MODEL: RENORMALIZABLE
