Implications of the Quark Mass Hierarchy on Flavor Mixings
We stress that the observed pattern of flavor mixings can be partly
interpreted by the quark mass hierarchy without the assumption of specific
quark mass matrices. The quantitatively proper relations between the
Kobayashi-Maskawa matrix elements and quark mass ratios, such as are obtainable from a simple {\it
Ansatz} of flavor permutation symmetry breaking at the weak scale. We prescribe
the same {\it Ansatz} at the supersymmetric grand unified theory scale, and
find that its all low-energy consequences on flavor mixings and violation
are in good agreement with current experimental data.Comment: Latex 19 pages including 5 PS figure
