Precise predictions formt,Vcb, andtanβ

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 that are substantially altered, $m_t$ and $tan\beta$, are displayed, including the dependence on the input $\left|V_{\mathrm{cb}}\right|$, $m_c$, $m_b$, and ${\alpha }_s$. A simple restriction on this framework yields an additional prediction for $\left|V_{\mathrm{cb}}\right|$. If the $b$, $t$, and $\tau$ Yukawa couplings are equal at the GUT scale then $\left|V_{\mathrm{cb}}\right|$ is predicted and the top quark mass is constrained to lie in the range $m_t=179\mathrm{}\pm 4$ GeV.
