Color screening masses from string models

TL;DR

This paper employs gauge/string duality to estimate the Debye screening mass at finite temperature and chemical potential, comparing results with holography and lattice QCD to enhance understanding of screening phenomena.

Contribution

It introduces a novel approach to estimate the Debye screening mass using string models within gauge/string duality, extending previous methods to finite temperature and chemical potential.

Findings

Debye mass estimated via string models aligns with holography results.

Comparison shows consistency with lattice QCD data.

Provides insights into screening effects in strongly coupled plasmas.

Abstract

We use gauge/string duality to estimate the Debye screening mass at non-zero temperature and baryon chemical potential. We interpret this mass as the smallest one in the open string channel. Comparisons are made with the results from holography and lattice QCD.
