Monopole density around static color sources

TL;DR

This paper investigates how magnetic monopole densities in quenched QCD are affected by static color sources, revealing suppression near sources and within flux tubes, thus shedding light on the vacuum structure related to confinement.

Contribution

It provides the first detailed analysis of monopole density distributions around static sources in quenched QCD, highlighting their suppression in the presence of external color charges.

Findings

Monopole density is suppressed near static sources.

In the confinement phase, monopole density decreases along the flux tube.

Results support the monopole condensation picture of confinement.

Abstract

We analyze the vacuum structure with respect to magnetic monopoles of quenched QCD in the presence of static color sources. Distributions of the monopole density around static quarks and mesons are computed in both phases of QCD. We observe a suppression of the monopole density in the vicinity of external sources. In the confinement phase the density of color magnetic monopoles is reduced along the flux tube between a static quark-antiquark pair.
