论文摘要
最近在$ b $和$ c $衰减中持续的超出标准模型效果的搜索中，有两个主题提高了：测试Lepton风味普遍性（LFU）以及Lepton风味（LFV）的可观察物。一组连贯的测量值表明非标准的LFU效应。一般论点将LFU与LFV有关，而观察到的前者的大小为后者带来了可观察的信号。我们尝试对这些测试的理论和实验方面进行全面讨论。最后的最后一条消息是，由于运行实验及其升级，所有充分建立推定的新效果所需的所有工具都将在手头。因此，该主题具有具体的机会，以引入真正意外的发现。
Two topics have recently risen to prominence within the ongoing searches of beyond-Standard Model effects in $b$ and $c$ decays: observables that test lepton flavor universality (LFU) as well as lepton flavor violation (LFV). A coherent set of measurements suggests non-standard LFU effects. General arguments relate LFU to LFV, and the observed size of the former gives hope of observable signals for the latter. We attempt a comprehensive discussion of both theoretical and experimental aspects of these tests. The main final message is that all the instruments necessary to fully establish the putative new effects are at hand, thanks to running experiments and their upgrades. Therefore this subject stands concrete chances to usher genuinely unexpected discoveries.
