带电轻子的辐射跷跷板机制

Radiative Seesaw Mechanism for Charged Leptons

Cheng-Wei Chiang, Kei Yagyu

摘要:

我们讨论了一种机制,带电轻子质量来自一个循环图介导的粒子在一个黑暗的部门,包括一个暗物质候选人。我们专注于一个场景中产生的μ子和电子质量在一个循环与新的${\cal O}(1)$汤川耦合。测量的μ子异常磁偶极矩,$(g-2)_μ$,可以解释在这个框架。作为一个重要的预测,μ子和电子汤川耦合可以在很大程度上偏离他们的标准模型预测,这种偏差可以在高亮度LHC和未来的$e^+e^-$对撞机进行测试。

英文摘要:

We discuss a mechanism where charged lepton masses are derived from one-loop diagrams mediated by particles in a dark sector including a dark matter candidate. We focus on a scenario where the muon and electron masses are generated at one loop with new ${\cal O}(1)$ Yukawa couplings. The measured muon anomalous magnetic dipole moment, $(g-2)_μ$, can be explained in this framework. As an important prediction, the muon and electron Yukawa couplings can largely deviate from their standard model predictions, and such deviations can be tested at High-Luminosity LHC and future $e^+e^-$ colliders.
