A priori definition of maximal CP nonconservation.

We define maximal CP nonconservation as occurring when a unique convention-independent parameter t, a quartic function of the Kobayashi-Maskawa matrix V, is maximized. The maximum value is much greater than the experimental upper limit, and so the observed CP nonconservation is much less than maximal. Maximal CP nonconservation corresponds to maximum mixing of the quark generations, just as maximal parity nonconservation corresponds to maximum mixing of the vector and axial-vector interactions.
