Predictions for constrained minimal supersymmetry with bottom-quark–τ mass unification

Abstract
We examine the constrained minimal supersymmetric standard model (CMSSM) with an additional requirement of strict b-τ unification in the region of small tanβ. 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-τ unification assumption. We also comment on the effect of a constraint from the nonobservation of proton decay.
