Effective action in general chiral superfield model

Abstract

The effective action in general chiral superfield model with arbitrary kählerian potential $K(\bar{\Phi },\Phi )$ and chiral (holomorphic) potential $W(\Phi )$ is considered. The one-loop and two-loop contributions to kählerian effective potential and two-loop (first non-zero) contribution to chiral effective potential are found for arbitrary form of functions $K(\bar{\Phi },\Phi )$ and $W(\Phi )$. It is found that despite the theory is non-renormalizable in general case two-loop contribution to holomorphic effective potential is always finite.
