Confinement from new global defect structures

TL;DR

This paper explores how new global defect structures in scalar field models can induce confinement in three-dimensional theories, resembling QCD, with monopole-like defects generating Coulomb and confining potentials.

Contribution

It introduces novel global defect solutions in scalar field theories that can produce confinement effects similar to those in QCD, including Coulomb and confining potentials.

Findings

Global defects induce confinement in scalar field models.

Monopole-like defects generate Coulomb potential.

Defects create confining potentials in effective theories.

Abstract

We investigate confinement from new global defect structures in three spatial dimensions. The global defects arise in models described by a single real scalar field, governed by special scalar potentials. They appear as electrically, magnetically or dyonically charged structures. We show that they induce confinement, when they are solutions of effective QCD-like field theories in which the vacua are regarded as color dielectric media with an anti-screening property. As expected, in three spatial dimensions the monopole-like global defects generate the Coulomb potential as part of several confining potentials.
