标题： Selection rules for charged lepton flavour violating processes from residual flavour groups

摘要： 我们系统地研究了带电轻子 sector 中残余味群可能产生的唯象学影响。 我们考虑了至 Z8 的所有可能的阿贝尔剩余对称性的味荷指派。 标准模型有效场论中算符允许的味结构（维度至六维）导致了带电轻子味破坏过程的独特且可观察到的模式。 我们通过展示对新物质量现有界限和未来灵敏度的选律相关性来说明这些结果。 这些结果尤其表明了对味破坏 τ 轻子衰变和 μonium 到反 μonium 转换的搜索的重要性及其鉴别能力。 显示英文摘要

摘要： We systematically investigate the possible phenomenological impact of residual flavour groups in the charged lepton sector. We consider all possible flavour charge assignments for abelian residual symmetries up to Z8. The allowed flavour structures of operators in Standard Model Effective Field Theory (up to dimension six) lead to distinctive and observable patterns of charged lepton flavour violating processes. We illustrate the relevance of such selection rules displaying the current bounds on and the future sensitivities to the new physics scale. These results demonstrate, in particular, the importance and discriminating power of searches for lepton flavour violating tau lepton decays and muonium to antimuonium conversion.
