Stringy instanton corrections to gauge couplings

We discuss a string model where a conformal four-dimensional gauge theory receives corrections to its gauge kinetic functions from “stringy” instantons. These contributions are explicitly evaluated by exploiting the localization properties of the integral over the stringy instanton moduli space. The...
