Exotic Hybrid Quark Potentials

TL;DR

This paper models exotic hybrid heavy-quark potentials using gauge/string duality, revealing that these potentials cannot be described by a single string and showing good agreement with lattice simulations for a specific case.

Contribution

It introduces a novel approach to modeling exotic hybrid quark potentials using gauge/string duality, expanding beyond traditional string models.

Findings

Good agreement with lattice simulations for ^- potential

Demonstrates that exotic potentials require multiple string descriptions

Provides new insights into heavy-quark potential modeling

Abstract

We use gauge/string duality to model some hybrid heavy-quark potentials. The potentials under consideration can't be described by a single Nambu-Goto string. This is why we call them "exotic". For $\Sigma_u^-$, the result is in quite good agreement with lattice simulations.
