STRUCTURE OF THE KOBAYASHI-MASKAWA MATRIX

The measure of CP violation J in the Kobayashi-Maskawa (KM) model is estimated by expansion around \V(ub)\ = 0. We obtain that \J\ congruent-to \V(us\\V(cb)\\V(ub)\ and the KM asymmetry parameter omega congruent-to -\V(us)\2\V(cb)\2. We discuss the implication of imposing this condition on the KM matrix elements, on the top-quark mass using the measurements Of epsilon(K), B(d-)0B(d)0BAR mixing, \V(cb)\, and \V(ub)\/\V(cb)\. A comparison with the symmetric KM matrix is made.
