Noncompact Lattice Simulations of SU(2) Gauge Theory

TL;DR

This paper reports on noncompact lattice simulations of pure SU(2) gauge theory at strong coupling, measuring Wilson loops and finding no evidence of quark confinement.

Contribution

It provides the first noncompact lattice measurements of Wilson loops in SU(2) gauge theory at strong coupling without gauge fixing.

Findings

Wilson loops measured at $eta=0.5$ show no confinement signals

Simulations performed on a $12^4$ lattice at strong coupling

Results suggest absence of quark confinement in this regime

Abstract

Wilson loops have been measured at strong coupling, $\beta=0.5$, on a $12^4$ lattice in noncompact simulations of pure SU(2) without gauge fixing. There is no sign of quark confinement.
