摘要

QCD轴是解决强CP问题的最具说服力的方案之一。与此同时，类型I seesaw机制为 observed neutrino 质量提供了优雅的解释;然而，其极重的Majorana态远远超出实验可达范围。低尺度替代方案，如逆seesaw，虽提高了可测试性，但通常缺乏强大的理论动机。在本文中，我们通过展示在标准模型内部结构自然产生的离散对称性 $\mathbb Z_4 \times \mathbb Z_3$ 所诱导的量子色轴，能够获得高质量的Peccei-Quinn对称性，从而自然地解决强CP问题，同时又同时又强制实施逆seesaw所需的场内容和层次结构。 resulting model is highly predictive and has the potential to be fully tested by future experiments. Beyond addressing the strong CP problem and the origin of neutrino masses, our scenario also contains a viable dark-matter candidate and offers potential mechanisms for generating the baryon asymmetry of the Universe.
