Monopoles and flux strings from SU(2) adjoint scalars

TL;DR

This paper constructs flux strings with monopoles at their ends in an SU(2) gauge theory with two adjoint scalars, demonstrating the flux saturation by monopoles through dualization and effective string variables.

Contribution

It introduces a novel model with sequential symmetry breaking producing monopoles and flux strings, and provides a dualized description showing flux saturation.

Findings

Flux strings with monopoles at ends are constructed.

Flux in strings is exactly saturated by monopoles.

Dualized theory describes effective string variables.

Abstract

We construct, in an SU(2) gauge theory with two adjoint scalars, flux strings with monopoles attached at the ends. One scalar breaks SU(2) to U(1) and produces monopoles, the other then breaks the U(1) and produces strings. Dualizing, we write the theory in terms of effective string variables and show that the flux in the string is exactly saturated by the monopoles at the ends.
