Screening in (2+1)D pure gauge theory at high temperatures

TL;DR

This paper calculates the heavy quark potential in a 2+1 dimensional pure gauge SU(3) theory at high temperatures and compares the results with perturbative predictions.

Contribution

It provides the first detailed comparison of non-perturbative heavy quark potentials with perturbative expectations in 2+1 dimensions at high temperatures.

Findings

Heavy quark potentials agree with perturbative calculations at high temperatures.

Results enhance understanding of confinement-deconfinement transition in lower dimensions.

Provides data for future theoretical and lattice studies.

Abstract

We compute heavy quark potentials in pure gauge $SU(3)$ at high temperatures in $2+1$ dimensions and confront them with expectations emerging from perturbative calculations.
