Non-perturbative SQCD Superpotentials from String Instantons
arXiv:hep-th/0612132 · doi:10.1088/1126-6708/2007/04/076
Abstract
The Affleck-Dine-Seiberg instanton generated superpotential for SQCD with Nf=Nc-1 flavours is explicitly derived from a local model of engineered intersecting D6-branes with a single E2-instanton. This computation extends also to symplectic gauge groups with Nf=Nc flavours.
