Abstract

It is shown that the mass matrices for both charges of quarks may be written in a most general form consistent with the data for quark masses and Kobayashi-Maskawa (KM) matrix elements. The most-general form is displayed explicitly for plausible choices of the masses and KM matrix elements. It is shown by direct calculation that in the good-CP limit there exists a basis for the quarks in which the squares of the elements of the up-quark mass matrix are proportional to the squares of the elements of the down-quark mass matrix. In this basis, the KM matrix is nontrivial solely because of differing signs of the mass-matrix elements.
