Non-Abelian Monopoles as the Origin of Dark Matter

摘要

We suggest that dark matter may be partially constituted by a dilute 'tHooft-Polyakov monopoles gas. We reach this conclusion by using theGeorgi-Glashow model coupled to a dual kinetic mixing term $ F{\tilde {\calG}}$ 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 interms of a dimensionless real parameter. This parameter could be determinedfrom milli-charged particle experiments.
