String loop corrections to gauge and Yukawa couplings

arXiv:hep-th/9301033

Abstract

We report on the recent progress in computing the effective supergravity action from superstring scattering amplitudes beyond the tree approximation. We discuss the moduli-dependent string loop corrections to gauge, gravitational and Yukawa couplings.
