Effective action in general chiral superfield model

Abstract

The effective action in general chiral superfield model with arbitrary kählerian potential $K(\barΦ,Φ)$ and chiral (holomorphic) potential $W(Φ)$ 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 $K(\barΦ,Φ)$ and $W(Φ)$. It is found that despite the theory is non-renormalizable in general case two-loop contribution to holomorphic effective potential is always finite.
