Mixing angles and CP violation in SU(2)/sub L/ x U(1) gauge model
Expressions for the mixing parameters are obtained in terms of mass ratios in the standard Weinberg-Salam model with permutation symmetry S/sub 3/ for six quarks. The CP-violating phase, delta, is taken into account, and there are no arbitrary parameters except for the quark masses. In the lowest order, the angles defined by Kobayashi-Maskawa are sin theta/sub 1/ approx. = (m/sub d//m sub d/ + m/sub s/)/sup 1/2, sin theta/sub 2/ approx. = -((m/sub s//m/sub b/)/sup 2/ - (m/sub c//m/sub t/)/sup 2/)/sup 1/2/, and sin theta/sub 3/ = (m/sub s//m/sub b/)/sup 2//cos theta/sub 1/. The model can be consistent with the observed magnitude of CP violation. The b quarks decay predominantly into c quarks with lifetime of tau/sub b/ approx. = 10/sup -11/ s.
