Non-Abelian monopoles as the origin of dark matter

摘要

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 (G) over tilde where F is the electromagnetic field and 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.
