Abstract

Supersymmetric gauge theories with Higgs mechanism are considered. After all heavy fields are integrated out we are left with the instanton-induced effective action for light fields. It is demonstrated that the one-loop instanton result is not modified by higher order perturbative corrections. The peculiarity of the case considered is that the background scalar fields do not possess definite chirality, and the bosonic and fermionic modes are not degenerate for this reason.
