论文摘要
我们描述了一种场景，中微子质量的较小与仅受量子重力效应侵犯的全球对称性有关。在此框架中，中微子与衡量单线右手式费米的耦合归因于对称保留重力算子，被普朗克质量抑制。提出的方案导致轴颗粒腐烂到中微子，可以通过宇宙学测量进行探测，并可能有助于解释哈勃参数张力。根据实施的详细信息，该方案可以提供斧头候选。
We describe a scenario where the smallness of neutrino masses is related to a global symmetry that is only violated by quantum gravitational effects. The coupling of neutrinos to gauge singlet right-handed fermions is attributed to symmetry preserving gravitational operators suppressed by the Planck mass, in this framework. The proposed scenario leads to axion particles that decay into neutrinos, which could be probed through cosmological measurements and may help explain the Hubble parameter tension. Depending on the details of the implementation, the scenario could provide axion dark matter candidates.
