论文摘要
ckm中的非零狄拉克阶段$δ^q $和$δ^l $，PMNS混合矩阵表示违反CP。通常，它们是独立的。但是，包括最近的T2K结果在内的实验数据表明，在混合矩阵的原始km参数化中，总和$δ^q _ {\ rm km} +δ^l _ {\ rm km} $与$δ^q _ {\ rm km km} $接近零。 KM参数化可能提供了一些暗示，这些阶段实际上是相关的，并且CP受到最大侵犯。我们表明，可以在自发违反CP的模型中适应此总和，在这种模型中，这两个阶段均来自非平凡的常见自发CP，在HIGGS潜力中违反了最大化相。我们发现，对于这种模型，对于改变风味的中性电流和CP违规而言，一些有趣的现象学后果。特别是，来自$ b_s的数据 - \ bar b_s $混合提供了模型中新的中性标量的质量尺度的非常强的限制，但是该模型仍然允许电子和中子的电偶极矩达到当前的上限。该模型可以通过不久的将来的实验进行测试。
The non-zero Dirac phases $δ^q$ and $δ^l$ in the CKM and PMNS mixing matrices signify CP violation. In general they are independent. Experimental data including recent T2K results show, however, that in the original KM parameterization for the mixing matrix, the sum $δ^q_{\rm KM} + δ^l_{\rm KM}$ is close to zero with $δ^q_{\rm KM}$ to be approximately $π/2$. The KM parameterization may have provided some hints that these phases are actually related and CP is maximally violated. We show that this sum rule can be accommodated in models with spontaneous CP violation where both phases originate from a non-trivial common spontaneous CP violating maximized phase in the Higgs potential. We find some interesting phenomenological consequences for flavor changing neutral current and CP violation for such a model. In particular, data from $B_s - \bar B_s$ mixing provide very strong constraints on the mass scale for the new neutral scalars in the model, yet the model still allows the electric dipole moments of electron and neutron to reach to their current upper bounds. The model can be tested by near future experiments.
