论文摘要
我们分析了中微子质量谱，并讨论了三个位点pati-salam模型的额外维修解释，i）i）统一所有夸克和叶子家族，ii）提供了对标准模型Yukawa耦合的自然描述，iii）可以说明最近的$ b $ phopysics anomalies。该模型的关键特征是pati-salam和Electroweak仪表对称性的破坏位于相对地点的对称性，并通过最近的邻居相互作用以减弱的方式传达给其他位置。我们表明，在这种情况下，在每个站点上本地将其纳入分层的主要质量质量量表，可以允许实现与数据一致的逆Seesaw机制，从而导致与数据一致的无政府主义中微子质量。这种三个站点设置的连续限制在带有三个缺陷的额外尺寸方面具有自然的解释，其中可以从$ \ Mathcal {O}（O}（1）$散装场质量的差异中实现所需的指数层次结构。
We analyze the neutrino mass spectrum and discuss the extra-dimensional interpretation of a three-site Pati-Salam model which i) unifies all families of quark and leptons, ii) provides a natural description of the Standard Model Yukawa couplings, iii) could account for the recent $B$-physics anomalies. The key feature of the model is a breaking of the Pati-Salam and electroweak gauge symmetries localized on opposite sites, communicated to the other sites in an attenuated manner via nearest-neighbor interactions. We show that in this context gauge-singlet fermions localized on each site, receiving hierarchical Majorana masses, can allow the implementation of an inverse seesaw mechanism leading to light anarchic neutrino masses consistent with data. The continuum limit of this three-site setup has a natural interpretation in terms of a warped extra dimension with three defects, where the required exponential hierarchies can be achieved from $\mathcal{O}(1)$ differences in the bulk field masses.
