摘要：

Within the framework of supersymmetric grand unification, estimates of the b quark mass based on the asymptotic relation m(b) similar or equal to m(tau) single out the region with tan beta close to unity, particularly if m(t)(m(t)) less than or similar to 170 GeV. We explore the radiative breaking of the electroweak symmetry and the associated sparticle and higgs spectroscopy in models with 1 < tan beta less than or similar to 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.
