We aim to explain the nature of neutrinos using Peccei-Quinn symmetry. We discuss two simple scenarios, one based on a type-II Dirac seesaw and the other in a one-loop neutrino mass generation, which solve the strong CP problem and naturally lead to Dirac neutrinos. In the first setup latest neutrino mass limit gives rise to axion which is in the reach of conventional searches. Moreover, we have both axion as well as WIMP dark mater for our second set up.

Peccei-Quinn对称性中的狄拉克中微子:两个例子

我们旨在使用Peccei-Quinn对称性解释中微子的性质。我们讨论了两种简单的情况,一种基于II型狄拉克跷跷板,另一种基于单回路中微子质量生成,它们解决了强CP问题并自然导致狄拉克中微子。在第一种设置中,最新的中微子质量极限会产生轴突,这是常规搜索所能达到的。此外,我们的第二个设置既有轴心也有WIMP深色材料。
