论文摘要
我们建议在[Arxiv：1910.05605V2，Arxiv：2004.06735V2]中提出的Orbifold理论中，暗物质，中微子质量和家庭对称性的共同起源。风味物理学是由$ a_4 $ family对称性描述的，这种对称性自然是由紧凑型产生的。 WIMP暗物质是从同一标量的第一个Kaluza-Klein激发中出现的，该标量通过逆向Seesaw机制驱动家庭对称性破裂和中微子质量。除了$0νβ$衰减的“黄金”夸克 - 莱普顿质量关系和中微子预测外，该模型还提供了对所有风味可观察物的良好全局描述。
We suggest a common origin for dark matter, neutrino mass and family symmetry within the orbifold theory proposed in [arXiv:1910.05605v2,arXiv:2004.06735v2]. Flavor physics is described by an $A_4$ family symmetry that results naturally from compactification. WIMP Dark matter emerges from the first Kaluza-Klein excitation of the same scalar that drives family symmetry breaking and neutrino masses through the inverse seesaw mechanism. In addition to the "golden" quark-lepton mass relation and neutrino predictions for $0νββ$ decay, the model provides a good global description of all flavor observables.
