Flavor Mixing, CP Violation and a Heavy Top

The recent analysis of the electroweak data at CDF indicates that the constraint on the top quark mass is $m_t=174\pm 17$GeV. We accommodate this result in a new scheme of quark mass matrices in which two elements along the the leading diagonal are non-vanishing and the other non-vanishing elements are those due to nearest neighbour interactions. By comparing the quark mixing matrix elements of our scheme with the experimentally determined Kobayashi- Maskawa matrix elememts in the standard electroweak model, we find that the CP violating phases ($\delta_1$ and $\delta_2$) in our model violate the CP symmetry maximally.
