In our previous paper, we examined a possibility of light WR in the framework of the SU(2)L ×SU(2)R ×U(1) model with spontaneous CP violation, by assuming a special form of the right-handed KM matrix KR in the CP conserving limit. Here we examine another possibility of KR. We show that the model allows MWR ≃400 ∼800 GeV depending on mt. In this model, the CP violations in K meson decays are due to the right-handed interaction. The model predicts both positive and negative values of ε'/ε, but its magnitude is smaller than 0.6 ×10-3 for MWR < 1 TeV. The electric dipole moment of neutron is predicted to be of order 10-27 e·cm. CP violating asymmetries in B meson decays are too small to be detected.

They discussed the bound on MWR from the neutrinoless double beta decay which is valid if νeR is heavy Majorana neutrino. We consider νeR to be a heavy Dirac neutrino (probably the Konopinski-Mahmoud Dirac particle formed with either νµR or ντR), or pseudo-Dirac neutrino to avoid this bound.
