In this paper, we study a non-renormalizable U(1)B−L extension of the Standard Model with D4 and Z4 symmetries accommodating the most recent neutrino data within the type-I seesaw mechanism. The two squared mass differences and three mixing angles can get the best-fit values while the leptonic Dirac CP phase is in 1σ range of the best-fit values for both normal and inverted orderings. The sum of active neutrino mass and the effective neutrino masses are, respectively, predicted to be ∑ mν = 60.03meV, 〈mee〉 = 2.307meV and 〈mβ〉 = 8.903meV for normal ordering while ∑ mν = 101.20meV, 〈mee〉 = 49.93meV and 〈mβ〉 = 49.95meV for inverted ordering, which are well consistent with the current experimental constraints.

具有 D4 × Z4 风味对称性的计量 B-L 模型中中微子质量和混合的 I 型跷跷板机制

在本文中，我们研究了一个不可重整化ü(1)乙-大号标准模型的扩展D4和Z4在 I 型跷跷板机制中容纳最新中微子数据的对称性。两个平方质量差和三个混合角可以获得最佳拟合值，而轻子狄拉克 CP 相处于1σ正常和反向排序的最佳拟合值范围。预计活性中微子质量和有效中微子质量之和分别为∑ 米ν = 60.03毫伏特,〈米ee〉 = 2.307毫伏特和〈米β〉 = 8.903毫伏特正常订购而∑ 米ν = 101.20毫伏特,〈米ee〉 = 49.93毫伏特和〈米β〉 = 49.95毫伏特对于倒序，这与当前的实验约束非常一致。
