Renormalization group equations for the Kobayashi-Maskawa matrix

Abstract

The renormalization group equations for the parametrization-convention independent quadratic parameters |Vij|2 of the KM matrix are derived. Numerical analysis of these equations shows that the heavy quark family (t, b) tends to mix with the lighter families (c, s) and (u, d) with increasing energy, although the variation is very much slow. The CP-nonconservation effects are shown to get larger with energy.
