The Center-Symmetric Phase of QCD
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.
