Magnetic Confinement in QCD

TL;DR

This paper provides strong evidence that magnetic monopole condensation in SU(2) QCD leads to dynamical symmetry breaking, supporting the dual Meissner effect as a mechanism for color confinement.

Contribution

It demonstrates that the one-loop effective action induces monopole condensation, offering a novel explanation for magnetic confinement in non-Abelian gauge theories.

Findings

Effective action induces monopole condensation.

Supports dual Meissner effect as confinement mechanism.

Separates topological and dynamical degrees in QCD.

Abstract

We present a strong evidence for the magnetic confinement in QCD by demonstrating that the one loop effective action of SU(2) QCD induces a dynamical symmetry breaking thorugh the monopole condensation, which could induce the dual Meissner effect and guarantee the confinement of color in the non-Abelian gauge theory. The result is obtained by separating the topological degrees which describes the non-Abelian monopoles from the dynamical degrees of the potential, and integrating out all the dynamical degrees of QCD.
