A study of center vortices in SU(2) and SU(3) gauge theories
M. Pepe (ETH), Ph. de Forcrand (ETH, CERN)
TL;DR
This paper investigates the role of center vortices and Abelian monopoles in SU(2) and SU(3) gauge theories, demonstrating their connection to gauge ambiguities and their impact on string tension in the continuum limit.
Contribution
It reveals how center vortices and monopoles emerge as gauge ambiguities and shows their significance in reproducing the full string tension in gauge theories.
Findings
Center vortices and monopoles are linked to gauge ambiguities.
Center-projected string tension matches the full string tension in the continuum limit.
Numerical results support the vortex and monopole picture in SU(2) and SU(3).
Abstract
We show how center vortices and Abelian monopoles both appear as local gauge ambiguities in the Laplacian Center gauge. Numerical results, for SU(2) and SU(3), support the view that the string tension obtained in the center-projected theory matches the full string tension when the continuum limit is taken.
