Abstract We study the mass spectrum of superparticles within supersymmetric grand unified models. For gaugino masses, it is pointed out that the GUT relation in the SU (5) model is applicable to a more general case where a grand-unified gauge group breaks dowm to the standard model gauge group by several steps. We also show that the mass spectrum of squarks and sleptons carries the information on the breaking pattern of the gauge symmetry. It is demonstrated in some SO (10) models how the… Expand

Probing SO(10) Symmetry Breaking Patterns Through Sfermion Mass Relations
We consider supersymmetric SO(10) grand unification where the unified gauge group can break to the Standard Model gauge group through different chains. The breaking of SO(10) necessarily involves theExpand
