摘要:

我们提出了一个基于$SU(3)_C\times SU(3)_L\times U(1)_X$规范对称性,辅以自发破缺的$U(1)_{L_g}$整体轻子数对称性和$S_3 \times Z_2 $离散群的可重整化理论,成功地描述了观测到的SM费米子质量和混合层次.在我们的模型中,顶夸克和奇异夸克得到树级质量,而底夸克、魅夸克和奇异夸克以及τ轻子和μ轻子由于与带电的奇异矢量(如费米子)混合而从树级通用跷跷板机制获得质量。第一代SM带电费米子的质量是由一个圈能级上的辐射跷跷板机制产生的。轻活性中微子质量是由一个环能级辐射跷跷板机制产生的。我们的模型成功地容纳电子和μ子异常磁偶极矩的实验值。

英文摘要:

We propose a renormalizable theory based on the $SU(3)_C\times SU(3)_L\times U(1)_X$ gauge symmetry, supplemented by the spontaneously broken $U(1)_{L_g}$ global lepton number symmetry and the $S_3 \times Z_2 $ discrete group, which successfully describes the observed SM fermion mass and mixing hierarchy. In our model the top and exotic quarks get tree level masses, whereas the bottom, charm and strange quarks as well as the tau and muon leptons obtain their masses from a tree level Universal seesaw mechanism thanks to their mixing with charged exotic vector like fermions. The masses for the first generation SM charged fermions are generated from a radiative seesaw mechanism at one loop level. The light active neutrino masses are produced from a loop level radiative seesaw mechanism. Our model successfully accommodates the experimental values for electron and muon anomalous magnetic dipole moments.
