论文摘要
我们探讨了在稀有的kaon衰变$ k \toπνν$中表现出的轻子量违规（LNV）的可能性，及其对辐射性中微子质量产生的后果以及在高规模卵生生成场景中的Lepton不对称性。我们在独立于模型的框架（标准模型有效场理论（SMEFT））中执行分析，并在当前在CERN的NA62实验的背景下讨论了稀有Kaon衰减的LNV性质。我们发现，在LNV相互作用的情况下，其检测将使高尺度的瘦素发生在张力下，并暗示辐射产生的中微子质量小。
We explore the possibility of lepton number violation (LNV) manifesting in the rare kaon decay $K\toπνν$, and its consequences for radiative neutrino mass generation and the washout of Lepton asymmetry in high-scale leptogenesis scenarios. We perform the analysis in a model-independent framework, the Standard Model effective field theory (SMEFT), and discuss the possible LNV nature of the rare kaon decay in the context of the currently operating NA62 experiment at CERN. We find that, in case of a LNV interaction, its detection would put high-scale leptogenesis under tension and would hint to small radiatively generated neutrino masses.
