论文摘要
在PQ对称性强化Lepton Number的情况下，我们探索了树级狄拉克中微子质量与轴心物理学之间的联系。要求PQ量表$ f_a $是唯一在中微子质量生成中发挥作用的唯一重型秤，我们被构建了KSVZ型模型，在该模型中，迪拉克中微子群众与$ f_a $相反，只要将真实的标量三重态（零增生）添加到SM Scalar部门。我们分析了这个扩展的标量扇区，重点是静电真空的稳定。三胞胎VEV对$ w $质量的贡献也可能是CDF合作的最新SM物理学的暗示。
We explore the connection between tree-level Dirac neutrino masses and axion physics in a scenario where the PQ symmetry enforces lepton number conservation perturbatively. Requiring that the PQ scale $f_a$ is the only heavy scale to play a role in neutrino mass generation, we are led to the construction of a KSVZ-type model where Dirac neutrino masses are inversely proportional to $f_a$, provided a real scalar triplet (zero hypercharge) is added to the SM scalar sector. We analyse this extended scalar sector, focusing on the stabilisation of the electroweak vacuum. The contribution of the triplet VEV to the $W$ mass may also be responsible for the recent hint of beyond-the-SM physics by the CDF collaboration.
