Abstract

We review some aspects of D‐instantons in intersecting D‐brane models. In particular, we present applications of the recently proposed instanton calculus to computations of charged matter superpotential couplings and corrections to the gauge kinetic function in the low energy effective action of type IIA orientifolds. As an interesting byway, we also discuss how one‐loop corrections to the gauge kinetic function can be deduced from gauge threshold corrections in the type IIA setting.

## Abstract We consider systems of magnetized D9 branes on orbifolds supporting 𝒩 = 1 gauge theories. In such realizations, the matter multiplets arise from “twisted” strings connecting different stacks of branes. The introduction of Euclidean 5‐branes wrapped on the six‐dimensional compact space l

## Abstract We review recent progress in the study of non‐rational (boundary) conformal field theories and their applications to describe exact holographic backgrounds in superstring theory. We focus mainly on the example of the supersymmetric coset __SL__(2, ℝ)/__U__(1), corresponding to the two‐d

## Abstract In this talk we discuss various aspects of the string landscape: D‐brane model building and their statistics, the generation of non‐perturbative superpotentials from D‐brane instantons, moduli stabilization by fluxes and non‐perturbative effects, the relation between flux vacua and BPS
