Abstract:

In the framework of the SU(2)L ×SU(2)R ×U(1) model with spontaneous CP violation, a possibility of light WR is examined. We constructed a model which allows MWR ∼400 GeV. This model shows quite different features from the standard model : (i) The CP violation in K →ππ decay is mainly from the right-handed interaction. (ii) The CP violations in Bd- \barBd mixing and the direct decays of Bd are small. In contrast, for the Bs meson the large CP asymmetries for both nonleptonic (20%) and semileptonic (20%) decays may appear through Bs-Bs mixing in some domain of MWR and mt. (iii) The electric dipole moment of neutron is as large as 10-26e ·cm .
