Abstract:

We examine the unitarity triangle of the KM matrix by using the general quark mass matrices on the NNI basis. The Fritzsch anz\"atz is modified by introducing four additional parameters. The KM matrix elements are expressed in terms of quark mass ratios, two phases and four additional parameters. It is found that the vertex of the unitarity triangle is predicted to be almost in the second quadrant on the

\rho -\eta

plane as far as

V_{us}\simeq -{\displaystyle \sqrt{\frac{m_d}{m_s}}e~{ip}+ \sqrt{\frac{m_u}{m_c}}e~{iq}}

is held.
