摘要：

We present analytic expressions for the top and bottom Yukawa couplings in the context of the minimal supersymmetric standard model when both couplings h(t,0), h(b,0) are large at the unification scale. For sufficiently large h(t,0), h(b,0), using as input the central value of the bottom mass m(b)(m(b)) = 4.25 GeV, we find that the top mass lies in the range m(t) almost-equal-to (174-178) GeV, while tan beta almost-equal-to (55-58). Implications on the evolution of the scalar masses and the radiative symmetry breaking scenario are discussed.
