在本文中，我们考虑了SM中的一组新的对称：对角反射对称。这些广义对称性预测的马约拉纳阶段或。对角反射对称性的实现意味着只有第一代的手征对称性破缺。轴子尺度建议为[GeV]。将对称性与四零织构相结合，得到了夸克和轻子的质量本征值和混合矩阵。该方案预测了正常的层次，狄拉克相位和或[meV]。在这个方案中，I型跷跷板机制和给定的中微子汤川矩阵完全决定了右手中微子质量的结构。统一预测质量本征值为[GeV]。
In this paper, we consider a set of new symmetries in the SM: diagonal reflection symmetries with diag . These generalized symmetries predict the Majorana phases to be or . Realization of diagonal reflection symmetries implies a broken chiral symmetry only for the first generation. The axion scale is suggested to be [GeV]. By combining the symmetries with the four-zero texture, the mass eigenvalues and mixing matrices of quarks and leptons are reproduced well. This scheme predicts the normal hierarchy, the Dirac phase and or [meV]. In this scheme, the type-I seesaw mechanism and a given neutrino Yukawa matrix completely determine the structure of the right-handed neutrino mass . A unification predicts the mass eigenvalues to be [GeV].
