摘要

最近，在对b和c衰变中超标准模型效应的持续研究中，有两个主题引起了人们的关注:测试轻子风味普适性(LFU)的观测值和测试轻子风味违和性(LFV)的观测值。一组连贯的测量表明，LFU效应是非标准的。一般的论点将LFU与LFV联系起来，前者的观测大小为后者提供了观测信号的希望。我们试图对这些测试的理论和实验方面进行全面的讨论。最后的主要信息是，所有必要的仪器，以充分建立假定的新效应是在手，感谢运行的实验和他们的升级。因此，这门学科很有可能带来真正意想不到的发现。

Lepton Flavor Violation and Lepton Flavor Universality Violation in b and c Decays

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) and those that test lepton flavor violation (LFV). A coherent set of measurements suggests nonstandard 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 a concrete chance of ushering in genuinely unexpected discoveries.
