Monopoles and Dyons in SU(5) Gauge Unification (with relation to a Dual Standard Model)

This article presents a fairly complete description of the monopoles and dyons arising from an SU(5) gauge unification of the standard model. Topics discussed include: the spectrum of SU(5) monopoles; their gauge equivalence structure; their spherical symmetry; the construction of dyons; global charge; the intrinsic angular momenta of scalar boson-monopole composites and monopole gauge excitations; and the effects of a theta vacuum. The relevance of each of these topics to constructing a dual description of the standard model with SU(5) solitons is discussed in detail.
