Abstract We investigate the pattern of CP violation in K0– K 0 , B0d– B 0 d and B0s– B 0 s mixing in a symmetrical SU(2)L×SU(2)R×U(1) model with spontaneous CP violation. From a set of fixed quark masses and mixings, we calculate the phases of the left and right quark mixing matrices beyond the small phase approximation and perform a careful analysis of all relevant restrictions on the model's parameters from ΔmK, ΔmB, ϵ, ϵ′/ϵ and the CP asymmetry aCP in B0d→J/ψK0S. Of 64 possible sets of…

It is led to conclude that the calculation of the box diagrams in the 't Hooft--Feynman gauge does give the major contribution as in this gauge other finite contributions would depend on physical-Higgs-boson masses or be suppressed by further Yukawa coupling constants.
