Confinement of monopole using flux string

TL;DR

This paper investigates how fermionic magnetic monopoles are confined by flux tubes in the Abelian Higgs model, emphasizing the necessity of multiple fermion species due to parity constraints.

Contribution

It demonstrates the confinement mechanism of monopoles via flux strings and highlights the requirement of at least two fermion species for model consistency.

Findings

Monopoles are confined by flux tubes in the Abelian Higgs model.

Parity symmetry imposes axial monopole currents.

Model consistency requires at least two fermion species.

Abstract

We study the confinement of fermionic magnetic monopoles by a thin flux tube of the Abelian Higgs model. Parity demands that the monopole currents be axial. This implies that the model is consistent only if there are at least two species of fermions being confined.
