Supersymmetric Models With Tan(beta) Close to Unity

Abstract

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