D‐brane instantons in 4D supersymmetric string vacua
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, …
