Abstract
We study the implications of a scalar bottom quark, with a mass of , within the minimal supersymmetric standard model. Light sbottoms may naturally appear for large and, depending on the decay modes, may have escaped experimental detection. We show that a light sbottom cannot be ruled out by electroweak precision data and the bound on the lightest -even Higgs-boson mass. We infer that a light scenario requires a relatively light scalar top quark whose mass is typically about the top-quark mass. In this scenario the lightest Higgs boson decays predominantly into pairs and obeys the mass bound .
