TL;DR

This paper studies monopole currents in high-temperature SU(2) QCD, revealing their significance for spatial string tension and their persistence in the continuum limit, which may relate to confinement mechanisms.

Contribution

It provides new insights into the behavior of monopole currents in the high-temperature phase of SU(2) QCD and their role in confinement phenomena.

Findings

Wrapped monopole currents are crucial for spatial string tension.

Monopole current density remains non-zero in the continuum limit.

Results connect monopole behavior to Polyakov's confinement analysis.

Abstract

We investigated a behavior of monopole currents in the high temperature phase of abelian projected finite temperature SU(2) QCD in maximally abelian gauge. Wrapped monopole currents which are closed by periodic boundary play an important role for the spatial string tension. And the wrapped monopole current density seems to be non-vanishing in the continuum limit. These results may be related to Polyakov's analysis of the confinement mechanism using monopole gas in 3-dimensional SU(2) gauge theory with Higgs fields.
