The profile of the broken string in the confined and deconfined phase in full QCD

TL;DR

This paper investigates how the flux tube profile in full QCD changes across the finite temperature phase transition, revealing the disappearance of the flux tube in deconfinement and its partial persistence near T_c.

Contribution

It provides a detailed analysis of the flux tube behavior in full QCD across different temperature phases, highlighting the transition characteristics.

Findings

Flux tube disappears in the deconfinement phase.

Near T_c, flux tube forms at short distances but vanishes at larger distances.

Electric field becomes Coulomb-like above T_c.

Abstract

We study the profile of the broken string (flux tube) in the maximally abelian gauge below and above the finite temperature phase transition in full QCD. In the deconfinement phase, the flux tube disappears and the electric field apperas to be Coulomb-like. In the confinement phase, but near $T_c$, at shorter distances a flux tube is formed like at zero temperature, while at larger distances the tube disappears similar to the deconfinement phase.
