Screening in the QCD plasma: effects of the gluons and of the confinement

TL;DR

This paper investigates how gluons and confinement influence screening effects in a QCD plasma, highlighting differences between gluon-mediated interactions and confinement phenomena.

Contribution

It introduces a simplified model analyzing the interplay between Debye screening and confinement in a thermalized gluon gas within a QCD plasma.

Findings

Gluon effects on screening are similar but not identical to electric screening.

Confinement significantly alters screening behavior compared to gluon exchange.

Phenomenological confinement leads to markedly different screening results.

Abstract

The effects of a thermalized gas of gluons in a q,q bar plasma is investigated. Then the interplay between Debye screening and confinement is analyzed in a simplified model. While the one-gluon exchange gives results very similar, but not equal, to the electric case, the phenomenological introduction of confinement leads to very different results.
