On the 1-loop Effective Action of String Compactifications

Abstract

In this talk, the speaker will review the status of 1-loop corrections to the effective action of certain 4-dimensional string theory models with N=1 supersymmetry. Concretely, he will mainly focus on the moduli sector and discuss 1-loop corrections to their sigma model metric, which plays an important role in model building. Some emphasis will be put on recent results concerning field redefinitions of the moduli fields which are enforced at string 1-loop level in order to comply with supersymmetry.
