摘要

The fermion mass and mixing angle predictions of a recently proposed framework are investigated for large b and τ\tau Yukawa couplings. A new allowed region of parameters is found for this large tanβ\tan \beta case. The two predictions which are substantially altered, mtm_t and tanβ\tan \beta, are displayed, including the dependence on the inputs Vcb|V_{cb}|, mcm_c, mbm_b and αs\alpha_s. A simple restriction on this framework yields an additional prediction, for Vcb|V_{cb}|. If the b,t, and τ\tau Yukawas are equal at the GUT scale then \Vcb|\Vcb| is predicted and the top quark mass is constrained to lie in the range \mt=179.±4.\mt = 179. \pm 4. GeV.
