# Monopoles and Spatial String Tension in the High Temperature Phase of SU(2) QCD

## TL;DR

This study investigates the role of monopole currents in the high-temperature phase of SU(2) QCD, revealing their significance in the spatial string tension and potential links to confinement mechanisms.

## Contribution

It provides new insights into monopole behavior and their impact on spatial string tension in the deconfinement phase of SU(2) QCD.

## Key findings

- Wrapped monopole currents are crucial for spatial string tension.
- Monopole current density remains non-zero in the continuum limit.
- Results suggest a connection to Polyakov's monopole gas model.

## Abstract

We studied a behavior of monopole currents in the high temperature (deconfinement) phase of abelian projected finite temperature SU(2) QCD in maximally abelian gauge. Wrapped monopole currents closed by periodic boundary play an important role for the spatial string tension which is a non-perturbative quantity in the deconfinement phase. 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.
