Dark Monopoles in Grand Unified Theories
We consider a Yang-Mills-Higgs theory with gauge group broken to
by a Higgs field in the adjoint
representation. We obtain monopole solutions whose magnetic field is not in the
Cartan Subalgebra. Since their magnetic field vanishes in the direction of the
generator of the electromagnetic group , we call them Dark
Monopoles. These Dark Monopoles must exist in some Grand Unified Theories
(GUTs) without the need to introduce a dark sector. We analyze the particular
case of GUT, where we obtain that their mass is , where is a
monotonically increasing function of with
and We also give a
geometrical interpretation to their non-abelian magnetic charge.Comment: 22 pages; added some comments on possible cosmological implications
of Dark Monopoles in the last section and added some references. Published
