CP破坏可以发生在标量扇区中具有自然味守恒(NFC)的规范模型的水平规范玻色子扇区中。在模型中,我们对中性K介子区的CP破坏参数e和e′/e以及中子的电偶极矩(dn)进行了显式计算,沿着通常的中性介子混合.对于参数空间的整个范围,其中模型与当前关于e的实验数据一致,人们获得参数e′/e和dn的非常小的值。
CP-violation can occur in the horizontal gauge boson sector of an gauge model with natural flavor conservation (NFC) in the scalar sector. We perform explicit calculations in the model of the CP-violating parameters e and e′/e in the neutral kaon sector and of the electric dipole moment of the neutron (dn), along with the usual neutral meson mixings. For the full range of parameter space where the model is consistent with current experimental data on e, one obtains very small values for the parameters e′/e and dn.
