论文摘要
在本文中，我们研究了Lepton质谱，风味混合和CP违规与模块化的$ S^{} _ 4 $对称性在中微子是Dirac Fermions的假设下。我们发现，通过调整右手中微子超级场的重量，可以禁止Majorana质量术语。我们研究了中微子部门模块化形成最低的非平凡重量二的场景，而带电的莱普顿部门中的模块化则从两个到六个到六。还详细讨论了从重新规范化组运行效应到我们的模型的校正。我们完全获得了十二种不同类别的模型，发现其中十个可以容纳当前的中微子振荡数据。
In this paper, we investigate lepton mass spectra, flavor mixing and CP violation with a modular $S^{}_4$ symmetry under the assumption that neutrinos are Dirac fermions. We find that the Majorana mass term can be forbidden by adjusting the weight of the right-handed neutrino superfields. We study the scenarios where modular forms in the neutrino sector take the lowest non-trivial weight two, while those in the charged-lepton sector vary from two to six. The corrections from renormalization-group running effects to our model have also been discussed in detail. We totally obtain twelve different classes of models and find that ten of them can accommodate current neutrino oscillation data.
