Quasi particles in hot QCD

TL;DR

This paper explores the behavior of spatial 't Hooft and Wilson loops in hot QCD plasma, linking them to chromo electric flux and magnetic quasiparticles, with predictions confirmed by recent simulations.

Contribution

It introduces a quasi-classical model connecting 't Hooft and Wilson loops to electric and magnetic quasiparticles in high-temperature QCD.

Findings

Predicted ratios of multiply charged Wilson loops match simulations.

Spatial 't Hooft loop behavior relates to chromo electric flux.

Wilson loop behavior modeled by nearly free magnetic quasiparticles.

Abstract

We show at very high temperature how the behaviour of the spatial 't Hooft loop in the QCD plasma is simply related to the chromo electric flux of the gluons. This simple picture is vindicated by a systematic quasi classical approach. The spatial Wilson loop 's behaviour is computed by a similar nearly free plasma of magnetic quasiparticles. This model predicts unambiguously ratios of multiply charged Wilson loops. Recent simulations confirm these predictions accurately.
