AI 中文摘要
带电轻子味破坏（Charged Lepton Flavor Violation, CLFV）的寻找是探测超出标准模型（Beyond the Standard Model, BSM）物理的有力工具。本章对CLFV理论进行全面综述，主要聚焦低能缪子和陶子的跃迁，同时概述高能对撞机的互补寻找。基于有效场论（Effective Field Theory, EFT）框架，我们系统评述关键可观测量，包括缪子和陶子的辐射衰变、纯轻子衰变，以及原子核内的μ→e转换和陶子强子衰变道。还讨论了涉及轻新物理粒子的CLFV。本综述体现了EFT、新型轻媒介子场景与强子、核物理在持续探寻BSM信号中的现代协同作用。
英文摘要
Searches for Charged Lepton Flavor Violation (CLFV) are powerful tools to probe physics beyond the Standard Model (BSM). This chapter provides a comprehensive survey of CLFV theory, focusing primarily on low-energy muon and tau transitions while outlining complementary searches from high-energy colliders. Grounded in the Effective Field Theory (EFT) framework, we systematically review key observables including radiative and purely leptonic decays of muon and tau as well as $μ\to e$ conversion in nuclei and $τ$ hadronic decay channels. CLFV involving light new physics particles is also discussed. This review captures the modern synergy between EFTs, novel light-mediator scenarios, and hadronic and nuclear physics in the ongoing hunt for BSM signals.
