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.

我们分析了中微子质谱并讨论了三点 Pati-Salam 模型的超维解释，该模型 i) 统一了所有夸克和轻子家族，​​ii) 提供了标准模型 Yukawa 耦合的自然描述，iii) 可以解释对于最近的B- 物理异常。该模型的关键特征是破坏了位于相对站点的 Pati-Salam 和电弱规范对称性，通过最近邻相互作用以衰减的方式与其他站点通信。我们表明，在这种情况下，定位在每个站点上的规范单线态费米子接收分层的马约拉纳质量，可以实现反向跷跷板机制，导致与数据一致的轻无政府中微子质量。这种三站点设置的连续限制在具有三个缺陷的扭曲额外维度方面具有自然的解释，其中所需的指数层次结构可以从$\mathcal{哦}(1)$ 体场质量的差异。
