引力相互作用和中微子质量

Gravitational Interactions and Neutrino Masses

Hooman Davoudiasl

摘要:

我们描述了一种情况下,中微子质量的小是有关的全球对称性,只有违反量子引力效应。在这个框架中,中微子与规范单重态右手费米子的耦合归因于普朗克质量所抑制的对称性保持引力算符。这种假设导致轴子粒子衰变为中微子,这可以通过宇宙学测量来探测,并可能有助于解释哈勃参数张力。根据实现的细节,该方案可能提供轴子暗物质候选者。

英文摘要:

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.
