QCD String as Vortex String in Seiberg-Dual Theory

TL;DR

This paper constructs a classical vortex string solution in a Seiberg-dual supersymmetric SO(N_c) QCD theory, demonstrating its stability and identifying it as a QCD string in the confining phase.

Contribution

It introduces a stable vortex string solution in the Seiberg-dual of N=1 supersymmetric SO(N_c) QCD, linking vortex strings to QCD strings in a confining regime.

Findings

Vortex strings are stable in the Seiberg-dual theory.

The vortex string solution is identified as a QCD string.

Supports the idea that vortex strings can represent QCD flux tubes.

Abstract

We construct a classical vortex string solution in a Seiberg-dual theory of N=1 supersymmetric SO(N_c) QCD which flows to a confining phase. We claim that this vortex string is a QCD string, as previouly argued by M.Strassler. In SO(N_c) QCD, it is known that stable QCD strings exist even in the presence of dynamical quarks. We show that our vortex strings are stable in the Seiberg-dual theory.
