Another weak first order deconfinement transition: three-dimensional SU(5) gauge theory

TL;DR

This study investigates the nature of the deconfinement phase transition in (2+1)-dimensional SU(5) Yang-Mills theory, revealing a weak first order transition consistent with expectations for large gauge groups.

Contribution

The paper provides non-perturbative lattice simulation evidence that the deconfinement transition in SU(5) gauge theory is weakly first order, supporting the idea that large gauge groups tend to have first order transitions.

Findings

Transition is weakly first order

Supports large gauge group behavior

Fits with theoretical expectations

Abstract

We examine the finite-temperature deconfinement phase transition of (2+1)-dimensional SU(5) Yang-Mills theory via non-perturbative lattice simulations. Unsurprisingly, we find that the transition is of first order, however it appears to be weak. This fits naturally into the general picture of "large" gauge groups having a first order deconfinement transition, even when the center symmetry associated with the transition might suggest otherwise.
