论文摘要
我们提出了一种模型，该模型采用$ CP \ times z_3 $对称性，其中通过遵循某些纹理来解释夸克混合和带电的瘦小质量。为了实现中微子的质量和混合，我们通过假设$ {\ Mathcal {o}}（1）$耦合预测否$ cp $违规，使用$ {\ Mathcal {o}}（1）使用类型的Lagrangian编写了不可鉴定的Lagrangian。然后，我们计算中微子质量正常和倒数排序的耦合值。我们提出了一种超紫（UV）完成的机制，该机制激发了中微子部门中较高维度的拉格朗日语。我们还计算了违反三胞胎标量驱动的模型的衰减的分支分支。后来，可以表明该模型还可以通过自发打破$ cp $对称性来容纳最大$ cp $违规。
We present a model which employs $CP\times Z_3$ symmetries where quark mixing and charged leptons masses are explained by following some texture. To achieve neutrino mass and mixing, we write a non-renormalizable Lagrangian using type-II seesaw mechanism by assuming ${\mathcal{O}}(1)$ couplings predicting no $CP$ violation. Then, we calculate the value of the couplings for both normal and inverted ordering of neutrino masses. We propose a mechanism of ultra-violet (UV) completion that motivates the higher dimensional Lagrangian in the neutrino sector. We also calculate the branching fraction of lepton flavor violating decays driven by triplet scalar for the model. Later, it is shown that the model can also accommodate maximal $CP$ violation by breaking the $CP$ symmetry spontaneously.
