Magnetic monopoles with internal structure

TL;DR

This paper explores magnetic monopoles within an extended non-Abelian model, revealing solutions with internal structure and compact spatial profiles through modified dynamics of gauge fields.

Contribution

It introduces a novel extension of the 't Hooft-Polyakov monopole model by adding a neutral field, leading to monopoles with internal structure and compact support.

Findings

Monopoles with internal structure are constructed in the extended model.

Solutions exhibit compact spatial profiles due to modified dynamics.

The model provides a new pathway to study monopoles with internal features.

Abstract

We investigate the presence of magnetic monopoles in a model that extends the non Abelian model originally studied by 't Hooft and Polyakov with the inclusion of an extra neutral field. The investigation includes modifications of the dynamics of the gauged fields, and the main results unveil a route to construct solutions that engender internal structure and live in a compact space.
