标题： CP-violating Phenomena in an $ SU(2)_L \times SU(2)_R \times U(1)_{B-L} \times SU(3)_H^{VL}$ Horizontal Symmetric Model

摘要： 我们考虑一个具有自然味守恒的Higgs部分的$SU(2)_L \times SU(2)_R \times U(1)_{B-L} \times SU(3)_H^{VL}$规范模型，其中CP破坏仅由于水平相互作用发生。 我们计算中性K介子部分的CP破坏可观测量$\epsilon$和$\epsilon'$以及中子的电偶极矩$d_n$。 产生与实验一致的$\epsilon$值的参数空间区域，对于$\epsilon'$和$d_n$的预测至少比当前实验上限小五个数量级。 显示英文摘要

摘要： We consider an $SU(2)_L \times SU(2)_R \times U(1)_{B-L} \times SU(3)_H^{VL}$ gauge model with natural flavour conservation in the Higgs sector, in which CP-violation occurs due to the horizontal interactions only. We calculate the CP-violating observables $\epsilon$ and $\epsilon'$ of the neutral kaon sector and $d_n$, the electric dipole moment of the neutron. The regions of the parameter space which yield a value of $\epsilon$ that is in agreement with the experiment, lead to predictions for $\epsilon'$ and $d_n$ which are at least five orders of magnitude smaller than the current experimental upper bounds.
