论文摘要
中微子质量提供了违反Lepton风味的证据，但尚未观察到被带电的瘦素之间的相互作用。标准模型（BSM）以外的许多物理模型都预测，充电的Lepton风味违规（CLFV）在各种过程中，随着即将进行的实验的速率。审查了CLFV搜索的当前最佳限制的实验搜索，并特别强调了基于MUON的实验，这些实验对BSM参数空间产生了最严格的约束。下一代基于MUON的实验（MEG-II，MU2E，Comet，MU3E）旨在通过W.R.T.的许多数量级进行改进。由于几个技术进步，当前的最佳限制。我们回顾了流行的重型BSM理论，并介绍了预测的CLFV分支比率的计算，重点是更灵敏的$μ\ \ e $ sector。
Neutrino masses provide evidence of lepton flavour violation, but no violation in the interactions among the charged leptons has been observed yet. Many models of Physics Beyond the Standard Model (BSM) predict Charged Lepton Flavour Violation (CLFV) in a wide spectrum of processes with rates in reach of upcoming experiments. The experimental searches that provide the current best limits on the CLFV searches are reviewed, with a particular emphasis on the muon-based experiments that give the most stringent constraints on BSM parameter space. The next generation of muon-based experiments (MEG-II, Mu2e, COMET, Mu3e) aim to reach improvements by many orders of magnitude w.r.t. the current best limits, thanks to several technological advancements. We review popular heavy BSM theories, and we present the calculations of the predicted CLFV branching ratios, focusing on the more sensitive $μ\to e$ sector.
