Abstract:

The fermion mass and mixing angle predictions of a recently proposed framework are investigated for large b and

\tau

Yukawa couplings. A new allowed region of parameters is found for this large

\tan \beta

case. The two predictions which are substantially altered,

m_t

and

\tan \beta

, are displayed, including the dependence on the inputs

|V_{cb}|

,

m_c

,

m_b

and

\alpha_s

. A simple restriction on this framework yields an additional prediction, for

|V_{cb}|

. If the b,t, and

\tau

Yukawas are equal at the GUT scale then |\Vcb| is predicted and the top quark mass is constrained to lie in the range \mt = 179. \pm 4. GeV.
