Confining Configurations in QCD and Relation to Rigid Strings

TL;DR

This paper explores the infrared configurations of QCD gauge fields using magnetic symmetry, revealing a dual Meissner effect and establishing a connection between the effective dual action and rigid string models.

Contribution

It introduces a magnetic symmetry-based approach to QCD infrared configurations and links the effective dual action to rigid string representations, offering new insights into confinement mechanisms.

Findings

Infrared QCD gauge fields satisfy magnetic symmetry conditions.

The effective dual action demonstrates a dual Meissner effect.

A string representation corresponds to a rigid string model.

Abstract

The gauge field configurations of QCD gauge fields in the infrared regime are obtained by magnetic symmetry condition. The effective dual action exhibits dual Meissner effect with quarks included. A string representation of this action corresponds to rigid string.
