论文摘要
我们在超对称$ su（5）$大统一理论的框架中提出了一个具有$ d_4 $风味对称性的模型。中微子质量来自I类型的机构，在该机构中，风味对称性的自发对称性破坏导致众所周知的三型混合（$ tm_2 $）。我们发现该模型预测了中微子质量的正常层次结构（NH）。我们还发现，可以在未来的中微子双β衰减实验中测试有效中微子质量$ m_ {ββ} $的预测范围。为了产生宇宙的重子不对称性（BAU），我们考虑了未经饮用的瘦素发生制度，并考虑到了三种持续的中微子$ n_i $的衰减。我们得出的结论是，BAU源自校正到狄拉克操作员，从而产生了新的耦合和$ CP $相位，这两者在生成观察到的BAU方面都起着重要作用。
We propose a model with $D_4$ flavor symmetry for leptogenesis in the framework of supersymmetric $SU(5)$ grand unified theory. Neutrino masses arise from the type I seesaw mechanism where the spontaneous symmetry breaking of the flavor symmetry leads to the well-known trimaximal mixing ($TM_2$). We find that this model predicts the normal hierarchy (NH) for neutrino masses. We also find that the predicted range of the effective neutrino mass $m_{ββ}$ can be tested at future neutrinoless double beta decay experiments. For the generation of the baryon asymmetry of the Universe (BAU), we consider the unflavored leptogenesis regime and we take into account the decay of the three righ-handed neutrinos $N_i$. We conclude that the BAU originates from a correction to the Dirac operator giving rise to a new coupling and a $CP$ phase which both play an important role in generating the observed BAU.
