Abstract

Within the framework of supersymmetric grand unification, estimates of the b quark mass based on the asymptotic relation m_b ≃ m_τ single out the region with tanβ close to unity, particularly if m_t(m_t) \stackrel_<_∼ 170 GeV. We explore the radiative breaking of the electroweak symmetry and the associated sparticle and higgs spectroscopy in models with 1 < tanβ\stackrel_<_∼ 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.
