Holomorphic Couplings In Non-Perturbative String Compactifications

Understand

In this review article we present an analysis of several aspects of four-dimensional, non-perturbative N=1 compactifications of string theory.

• Our study focuses on brane dynamics and their effective physics as encoded in the holomorphic couplings of the low-energy N=1 effective action, most prominently the superpotential W.
• This article is divided into three parts.
• In part one we derive the effective action of a spacetime-filling D5-brane in generic Type IIB Calabi-Yau orientifold compactifications.
