Predictions for constrained minimal supersymmetry with bottom-quark- tau mass unification.

Abstract

We examine the constrained minimal supersymmetric standard model (CMSSM) with an additional requirement of strict b-\ensuremath{\tau} unification in the region of small tan\ensuremath{\beta}. We find that the parameter space becomes completely limited below about 1 TeV by physical constraints alone, without a fine-tuning constraint. We study the resulting phenomenological consequences, and point out several ways of falsifying the adopted b-\ensuremath{\tau} unification assumption. We also comment on the effect of a constraint from the nonobservation of proton decay.
