Emergent phenomena from centre vortices in dynamical QCD

TL;DR

This paper reviews recent lattice QCD studies showing that centre vortices are fundamental to quark confinement and chiral symmetry breaking, highlighting their emergent role in the non-perturbative regime.

Contribution

It demonstrates the importance of centre vortices in full QCD by comparing vortex-removed and vortex-only fields, providing evidence for their role in key phenomena.

Findings

Vortex-removed fields lack confinement and chiral symmetry breaking.

Vortex-only fields reproduce essential non-perturbative features.

Comparisons support vortices as fundamental to QCD phenomena.

Abstract

Quark confinement and dynamical chiral symmetry breaking are two of the most important emergent properties of the theory of quantum chromodynamics. We review recent results studying centre vortices in SU(3) lattice gauge theory with dynamical quarks. Through a vortex identification procedure, vortex-removed and vortex-only fields are obtained from the usual Monte Carlo generated gauge fields. Several comparisons between the untouched fields and the vortex-modified fields support the notion that centre vortices are fundamental to both confinement and dynamical chiral symmetry breaking in full QCD.
