On Integrating Out Heavy Fields in SUSY Theories

TL;DR

This paper investigates the process of integrating out heavy fields in supersymmetric theories, highlighting necessary modifications to standard conditions and discussing their applicability, especially in string compactification contexts.

Contribution

It provides a revised framework for integrating out heavy fields in SUSY theories, addressing limitations of traditional methods and their relevance to string compactifications with fluxes.

Findings

Standard conditions need modification for SUSY theories.

Restrictions determine when traditional methods are valid.

Relevance to string compactification with fluxes.

Abstract

We examine the procedure for integrating out heavy fields in supersymmetric (both global and local) theories. We find that the usual conditions need to be modified in general and we discuss the restrictions under which they are valid. These issues are relevant for recent work in string compactification with fluxes.
