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 leads to instanton effects. We examine the interplay between the annuli diagrams with an E5 boundary and the holomorphicity properties of the effective low‐energy supergravity action which describes the system, including its instanton corrections. This talk is mostly based on [1].

## 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
