F.Lenz (University of Erlangen)
TL;DR
This paper explores the center-symmetric phase of SU(2) QCD, focusing on Polyakov loops, monopoles, and confinement mechanisms through non-perturbative gauge fixing and axial gauge analysis.
Contribution
It provides new insights into how center symmetry and confinement-like properties emerge from non-perturbative gauge fixing in SU(2) QCD.
Findings
Center symmetry realization results from non-perturbative gauge fixing.
Confinement-like properties appear even at the perturbative level.
Singular gauge configurations are an inevitable outcome of the gauge fixing process.
Abstract
An investigation of the center symmetric phase of SU(2) QCD is presented. The role of the center-symmetry, the dynamics of Polyakov loops and the structure of Abelian monopoles are studied within the axial gauge representation of QCD. Realization of the center symmetry is shown to result from non-perturbative gauge fixing and concomitant confinement like properties emerging even at the perturbative level are displayed. In an analysis of the Polyakov loop dynamics, non-perturbative gauge fixing is also shown to inevitably lead to singular gauge field configurations whose dynamics are briefly discussed.
