Lepton mixing patterns from the modular group PSL₂(7) with generalized CP symmetries are studied. The residual symmetries in both charged lepton and neutrino sectors are . Seven types of mixing patterns at the 3σ level of the new global fit data are obtained. Among these patterns, three types of patterns can give the Dirac CP phase which is in the 1σ range of the global fit data. The effective mass of neutrinoless double-beta decay for these patterns is also examined.

具有广义CP对称性的PSL2（7）的轻子混合模式

研究了具有广义CP对称性的模块化PSL ₂（7）组的轻子混合模式。带电的轻子和中微子扇区中的剩余对称是。在新的全局拟合数据的3σ级别获得了七种类型的混合模式。在这些模式中，三种类型的模式可以给出Dirac CP相位，该相位在全局拟合数据的1σ范围内。还检查了这些模式的无中微子双β衰变的有效质量。
