本文提出了一种基于$D_4$味对称性自发破缺的中微子质量与混合的逆跷跷板模型。该模型同时解释了观测到的中微子振荡模式、通过TeV尺度轻子生成产生的宇宙重子不对称性，以及可能可观测的带电轻子味破坏（cLFV）过程。唯象分析表明，该模型在正常和倒置质量排序下均与当前中微子振荡数据一致。对于最轻的赝狄拉克中微子质量在multi-TeV尺度时，可实现成功的轻子生成。预测的cLFV分支比远低于当前实验上限，同时处于下一代实验的灵敏度范围内。这些结果确立了该模型作为一个可行且可测试的框架，将低能中微子观测量与TeV尺度轻子生成及cLFV现象学联系起来。
英文摘要
An inverse seesaw model for neutrino masses and mixing is proposed, based on the spontaneous breaking of a $D_4$ flavor symmetry. The model simultaneously accounts for the observed neutrino oscillation pattern, the baryon asymmetry of the Universe through TeV-scale leptogenesis, and potentially observable charged-lepton flavor violating (cLFV) processes. A phenomenological analysis shows that the model is consistent with current neutrino oscillation data for both normal and inverted mass orderings. Successful leptogenesis is realized for lightest pseudo-Dirac neutrino masses at the multi-TeV scale. The predicted cLFV branching ratios lie well below the current experimental upper limits while remaining within the sensitivity reach of next-generation experiments. These results establish the model as a viable and testable framework that links low-energy neutrino observables to TeV-scale leptogenesis and cLFV phenomenology.
