On Exotic Hybrid Pseudo-Potentials and Gauge/String Duality

TL;DR

This paper employs gauge/string duality to model exotic hybrid pseudo-potentials in SU(N) gauge theories, revealing their non-string nature and demonstrating the universality of the spatial string tension.

Contribution

It introduces a novel approach to modeling exotic hybrid pseudo-potentials using gauge/string duality, highlighting their deviation from single-string descriptions.

Findings

Exotic pseudo-potentials cannot be described by a single Nambu-Goto string.

The spatial string tension exhibits universality across models.

The gauge/string duality provides a consistent framework for these pseudo-potentials.

Abstract

We use gauge/string duality to model some hybrid pseudo-potentials in a pure SU(N) gauge theory. The pseudo-potentials under consideration can't be described by a single Nambu-Goto string. This is why we call them "exotic". A comparison with the calculation of the pseudo-potential shows the universality of the spatial string tension.
