Abstract

We calculate the one‐loop corrections to gauge couplings in N = 1 supersymmetric brane world models, which are realized in an type IIA orbifold/orientifold background with several stacks of D6 branes wrapped on 3‐cycles with non‐vanishing intersections. Contributions arise from both N = 1 and N = 2 open string subsectors. In contrast to what is known from ordinary orbifold theories, N = 1 subsectors do give rise to moduli‐dependent one‐loop corrections.

## Abstract In this paper, which is based on the first part of the author's PhD thesis, we review the statistics of the open string sector in __T__^6^/(ℤ~2~ × ℤ~2~) orientifold compactifications of type IIA. After an introduction to the orientifold setup we discuss the two different techniques that

## Abstract The aim of this article is to review some recent progress in the field of intersecting D‐brane models. This includes the construction of chiral, semi‐realistic flux compactifications, the systematic study of Gepner model orientifolds, the computation of various terms in the low energy e
