Abstract
We consider the constraints from proton decay and b-τ unification in the minimal supersymmetric SU(5) grand unified theory with a ‘‘visible’’ dynamical supersymmetry-breaking sector. We show how the presence of vectorlike messenger fields and the constrained superparticle mass spectrum affect the phenomenology of the model. We include the messenger fields in our renormalization group analysis between the messenger scale (∼100 TeV) and the GUT scale. We show that the simplest model of this type, a minimal SU(5) GUT with an additional 5+5¯ of the messenger fields, is excluded by the constraints from proton decay and b-τ unification. © 1996 The American Physical Society.Keywords
