Abstract

Within the framework of supersymmetric grand unification, estimates of the bb quark mass based on the asymptotic relation mbmτm_b \simeq m_\tau single out the region with tanβ\tan\beta close to unity, particularly if mt(mt)<170 GeVm_t(m_t) \stackrel{_<}{_\sim} 170\ GeV. We explore the radiative breaking of the electroweak symmetry and the associated sparticle and higgs spectroscopy in models with 1<tanβ<1.61 < \tan\beta \stackrel{_<}{_\sim} 1.6. The lightest scalar higgs is expected to have a mass below 100 GeV100\ GeV, while the remaining four higgs masses exceed 300 GeV300\ GeV. The lower bounds on some of the sparticle masses are within the range of LEP 200.
