在这篇综述文章中,我们强调了包含味道对称性的模型对带电轻子违反味道(LFV)过程的影响。味道对称性提供了一种自然的方法来解释标准模型费米子的特殊质量等级和混合模式。LFV的新来源通常出现在超越标准模型的新物理中,而气味对称性可以对LFV可观测性做出独特的预测。他们的发现可以为区分味道对称性和新的物理场景提供关键信息。由于它们的高度敏感性,我们将集中在寻找低能的LFV过程,如在原子核中的μ→eγ或μ-e转换,但我们也将强调LFV过程在大型强子对撞机上的潜在影响。如果在大型强子对撞机能够达到的范围内出现新的物理现象,那么它们所引发的味道运算符可能会被更详细地探测。
In this review article, we highlight the impact of models incorporating flavour symmetries on charged lepton flavour violating (LFV) processes. Flavour symmetries provide a natural approach to explain the peculiar mass hierarchies and mixing patterns of the Standard Model fermions. New sources of LFV are generally present in new physics beyond the Standard Model, and flavour symmetries can make distinctive predictions for LFV observables. Their discovery can provide crucial information to distinguish flavour symmetries and new physics scenarios in general. Because of their high sensitivity, we will focus on searches for low‐energy LFV processes such as μ → e γ or μ‐e conversion in nuclei but we will also highlight the potential impact of LFV processes at the LHC. If new physics occurs at a scale accessible by the LHC, the flavour operators they induce could potentially be probed in high detail.
