Non-Abelian Monopoles as the Origin of Dark Matter

TL;DR

This paper proposes that dark matter could be explained by a gas of non-Abelian monopoles from the Georgi-Glashow model, with their properties influenced by a dual kinetic mixing term, potentially detectable via milli-charged particle experiments.

Contribution

It introduces a novel dark matter candidate based on non-Abelian monopoles with modified charge quantization, linking theoretical monopole properties to experimental tests.

Findings

Monopoles carry both electric and magnetic charges.

Electric charge quantization is modified by a new parameter.

Potential experimental detection through milli-charged particle experiments.

Abstract

We suggest that dark matter may be partially constituted by a dilute 't Hooft-Polyakov monopoles gas. We reach this conclusion by using the Georgi-Glashow model coupled to a dual kinetic mixing term $ F{\tilde {\cal G}}$ where $F$ is the electromagnetic field and ${\cal G}$ the 't Hooft tensor. We show that these monopoles carry both (Maxwell) electric and (Georgi-Glashow) magnetic charges and the electric charge quantization condition is modified in terms of a dimensionless real parameter. This parameter could be determined from milli-charged particle experiments.
