Signatures of Confinement in Axial Gauge QCD

TL;DR

This paper explores the confinement phenomena in axial gauge QCD by comparing it with QED, revealing how certain gluonic excitations are suppressed due to a dual Meissner effect, which explains the expulsion of chromo-electric fields.

Contribution

It provides a comparative analysis of axial gauge QED and QCD, highlighting the suppression of gluonic excitations and interpreting it as a dual Meissner effect related to confinement.

Findings

Gluonic excitations analogous to polarized photons acquire infinite energy.

Suppression of these excitations in QCD is due to quantization of chromoelectric flux.

The dual Meissner effect explains the expulsion of chromo-electric fields from the QCD vacuum.

Abstract

A comparative dynamical study of axial gauge QED and QCD is presented. Elementary excitations associated with particular field configurations are investigated. Gluonic excitations analogous to linearly polarized photons are shown to acquire infinite energy. Suppression of this class of excitations in QCD results from quantization of the chromelectric flux and is interpreted as a dual Meissner effect, i.e. as expulsion from the QCD vacuum of chromo-electric fields which are constant over significant distances. This interpretation is supported by a comparative evaluation of the interaction energy of static charges in the axial gauge representation of QED and QCD.
