Abstract
Within the framework of supersymmetric grand unification, estimates of the b quark mass based on the asymptotic relation mb mτ single out the region with β close to unity, particularly if mt(mt) < 170\ GeV. We explore the radiative breaking of the electroweak symmetry and the associated sparticle and higgs spectroscopy in models with 1 < β< 1.6. The lightest scalar higgs is expected to have a mass below 100\ GeV, while the remaining four higgs masses exceed 300\ GeV. The lower bounds on some of the sparticle masses are within the range of LEP 200.
