Stringy Instantons as Strong Dynamics

TL;DR

This paper explores how stringy instantons influence strong dynamics in type IIB toric quiver gauge theories, linking moduli space constraints with instanton effects across various gauge groups.

Contribution

It establishes a relation between stringy instanton contributions and classical moduli space constraints using Seiberg duality, applicable to multiple gauge group types.

Findings

Stringy instantons contribute to the superpotential in these theories.

The relation holds for unitary, orthogonal, and symplectic gauge groups.

Seiberg duality helps connect instanton effects with classical moduli space constraints.

Abstract

We study the relation between stringy instantons and strong dynamics effects in type IIB toric quiver gauge theories. By exploiting the involutive property of Seiberg duality we relate the classical constraint on the moduli space of the gauge theory with the stringy instanton contribution to the superpotential. The result holds for unitary, orthogonal and symplectic gauge groups.
