Confinement and Dynamical Symmetry Breaking in non-SUSY Gauge Theory from S-duality in String Theory

TL;DR

This paper explores how S-duality in string theory can shed light on confinement and symmetry breaking in non-supersymmetric gauge theories, proposing a dual magnetic description involving SO gauge groups.

Contribution

It introduces a novel approach linking S-duality in string theory to confinement and dynamical symmetry breaking in non-SUSY gauge theories via specific USp and SO gauge duals.

Findings

Confinement is explained through scalar field condensation in the magnetic dual.

The dual Meissner mechanism is supported by the proposed duality.

The magnetic dual theories are derived from O3-D3bar systems in string theory.

Abstract

We discuss an attempt to understand confinement and dynamical symmetry breaking in a 4-dimensional non-supersymmetric gauge theory using S-duality in type IIB string theory. The electric theory is a USp(2n) gauge theory and its magnetic dual is argued to be an SO(2n) or SO(2n-1) gauge theory. These theories are obtained as the low-energy effective theory of O3-D3bar systems in type IIB string theory, which are related by S-duality. Confinement and dynamical symmetry breaking in the USp(2n) gauge theory are caused by the condensation of scalar fields in the magnetic dual description, which is consistent with the scenario of the dual Meissner mechanism for the confinement.
