J. Greensite, S. Olejnik, and D. Zwanziger
TL;DR
This paper demonstrates through numerical analysis that the Coulomb self-energy of a color non-singlet source diverges in infinite volume, supporting the Gribov Horizon confinement scenario and linking divergence to center vortices.
Contribution
It provides numerical evidence connecting Coulomb self-energy divergence to the Gribov Horizon and center vortices in lattice Yang-Mills theory.
Findings
Coulomb self-energy diverges in infinite volume for non-singlet sources
Divergence is linked to the presence of center vortices
Supports the Gribov Horizon confinement scenario
Abstract
It is shown numerically that the Coulomb self-energy of an isolated, color non-singlet source diverges in an infinite volume. This is in accord with the Gribov Horizon scenario of confinement advocated by Gribov and Zwanziger. It is also shown that this divergence can be attributed to the presence of center vortices in thermalized lattice configurations.
