| dc.description | We study a class of quark mass matrix models with the $\cal CP$-violating phase determined through making the $\cal CP$-violating parameter $J$ an extremum. These models assume that $m_u \ll m_c \ll m_t$ and that $m_d \ll m_s \ll m_b$. They have $\left|{V_{ub}\over{V_{cb}}}\right|\approx{\sqrt{m_u \over{m_c}}}$, $\left|{V_{td}\over{V_{ts}}}\right|\approx{\sqrt{m_d \over{m_s}}}$ and $|V_{us}|\approx|V_{cd}|\approx{\sqrt{m_d \over{m_s}+{m_u \over{m_c}}}}$. The Wolfenstein parameters $ρ$ and $η$ are found to be related by $ρ\approxη^2$. Finally, we examine a special class of such models where the masses are constrained to be roughly in geometric progression. Further application of the extremal condition to $J$ then leads to ${\sqrt{m_d \over{m_s}}}\approx 3{\sqrt{m_u \over{m_c}}}$ and hence $η\approx\frac{1}{3}$, for maximal $J$. | |
