Gauge Instantons from Open Strings
arXiv:hep-th/0401062 · doi:10.1002/prop.200410151
Abstract
In this contribution we describe how to obtain instanton effects in four dimensional gauge theories by computing string scattering amplitudes in D3/D(-1) brane systems. In particular we show that the disks with mixed boundary conditions, which are typical of the D3/D(-1) system, are the sources for the classical instanton solution.
