Roy Wensley, John Stack
TL;DR
This paper investigates the roles of magnetic monopoles and center vortices in the confinement mechanism of SU(3) lattice gauge theory by computing the heavy quark potential and comparing string tensions.
Contribution
It introduces methods for identifying monopoles and vortices in SU(3) and compares their contributions to the quark potential with the full gauge theory.
Findings
Monopoles and vortices reproduce the full SU(3) string tension.
Center vortices are identified using an indirect gauge fixing scheme.
Magnetic monopoles are identified after maximal abelian gauge fixing.
Abstract
We present results for the heavy quark potential computed in SU(3) from magnetic monopoles and from center vortices. The monopoles are identified after fixing SU(3) lattice configurations to the maximal abelian gauge. The center vortices are identified after using an indirect center gauge fixing scheme which we describe for SU(3). Z(3) center vortices are extracted and used to compute the potential. The values of the string tensions from monopoles and vortices are compared to the full SU(3) string tension.
