论文摘要
在这项工作中，我们探讨了引力$θ$异常产生中微子质量的提议机制。我们强调，中微子冷凝物的主要可重新分解相互作用禁止产生与观察一致的分层质量的可能性。当考虑到标准型号循环更正时，此结论仍然存在。我们表明，高维操作员可以减轻此问题。可以从重力异常本身产生高维操作员，但是如果没有更深入了解这种机制的低能量描述，就没有明确的方法可以知道。因此，我们探讨了新粒子产生中微子质量分裂的可能性。我们表明，在中微子自我能源的环中，这两个新粒子都会改变冷凝物或新粒子的标量电势，均可解决这个问题。
In this work, we explore the proposed mechanism in which the gravitational $θ$ anomaly generates neutrino masses. We highlight that the leading renormalizable interactions of the neutrino condensate forbid the possibility of generating hierarchical masses consistent with observation. This conclusion still holds when Standard Model loop corrections are accounted for. We show that higher-dimensional operators can alleviate this problem. The higher-dimensional operators could be generated from the gravitational anomaly itself, but there is no clear way to know without a deeper understanding of the low-energy description of this mechanism. Because of that, we explore the possibility of new particles generating neutrino mass splittings. We show that both new particles that alter the scalar potential of the condensate or new particles in loops for the neutrino self-energy can solve this problem.
