Magnetic monopoles in high temperature QCD

TL;DR

This paper investigates the behavior and distribution of thermal Abelian monopoles in high-temperature SU(2) gauge theory, revealing their interactions and continuum properties in the deconfined phase.

Contribution

It provides a detailed analysis of monopole density and distribution in SU(2) gauge theory using the Maximal Abelian Gauge, addressing projection choices and continuum limits.

Findings

Monopoles exhibit non-trivial interactions.

Monopole density has a well-defined continuum limit.

Interactions suggest monopoles play a significant role in deconfined phase.

Abstract

We study the density and spatial distribution of thermal Abelian monopoles in the deconfined phase of SU(2) pure gauge theory: they display non-trivial interactions with a well defined continuum limit. The Maximal Abelian Gauge (MAG) has been chosen to perform the Abelian projection. Questions related to the choice of the Abelian projection, as well as possible directions for future studies, are discussed.
