AN ESTIMATE OF THE REPHASING-INVARIANT QUANTITY-J

The 3 x 3 Kobayashi-Maskawa matrix V is parametrized, without using a CP violation phase parameter explicitly, by four independent parameters alpha = \V(us)\, beta = \V(cb)\, gamma = \V(ub)\ and omega = \V(cd)\2 - \V(us)\2. The rephasing-invariant quantity J of CP nonconservation is estimated by means of extrapolation from J = 0 at gamma-2 = 0. It is speculated that absolute value of J congruent-to alpha-beta-gamma congruent-to 3.8 x 10(-5) and omega = -alpha-2-beta-2 congruent-to -9.4 x 10(-5).
