String breaking in a cold wind as seen by string models

TL;DR

This paper uses gauge/string duality to model how a heavy quark-antiquark pair's string breaking distance is affected by temperature and velocity in a cold medium, revealing slow variation away from critical conditions.

Contribution

It introduces a string model approach to analyze string breaking in a cold medium considering temperature and velocity effects, highlighting behavior near critical conditions.

Findings

String breaking distance varies slowly with temperature and velocity.

Distance may decrease significantly near the critical line.

Model provides insights into quark-antiquark interactions in cold media.

Abstract

Using the gauge/string duality, we model a heavy quark-antiquark pair in a color singlet state moving through a cold medium and explore the consequences of temperature and velocity on string breaking. We show that the string breaking distance slowly varies with temperature and velocity away from the critical line but could fall near it.
