论文摘要
搜索带电的Lepton违规侵犯（CLFV）为各种新物理场景提供了深入的探针，例如超对称模型，涉及标量leptoquarks或其他Higgs Doublets的理论，以及通过卵生成的中性质量等级制度和中微质量层次层次制度和中微质量质量层次制度和Mattle-Matter-Antimtertalsmetry。在细胞核领域，元素向电子的相干，中准的转化，$μ^{ - } +n \ rightarrow e^{ - } +n $，是对这种新物理学具有敏感性的Muonic CLFV过程的一个例子。本文详细介绍了三个实验：Comet，Deeme和Mu2e，将在未来十年中搜索$μ^{ - } +n \ rightArrow e^{ - } +n $。这些实验提供了$ \ Mathcal {O}（10^{4} $ tev/c $^{2} $）的有效新物理质量尺度的敏感性，远远超出了直接基于碰撞的，基于对撞机的搜索。提出了这三个实验的理论动机，设计和预期时间表。这些实验是全球搜索CLFV的关键部分。强烈鼓励对所有计划的实验搜索进行所有计划的实验搜索。
Searches for charged lepton flavor violation (CLFV) offer deep probes for a range of new physics scenarios, such as super-symmetric models, theories involving scalar leptoquarks or additional Higgs doublets, and models explaining the neutrino mass hierarchy and the matter-antimatter asymmetry of the universe via leptogenesis. The coherent, neutrinoless conversion of a muon to an electron in the field of a nucleus, $μ^{-}+N\rightarrow e^{-} +N$, is one example of a muonic CLFV process which has sensitivity to this new physics. This paper details three experiments: COMET, DeeMe and Mu2e which will search for $μ^{-}+N\rightarrow e^{-} +N$ in the coming decade. These experiments offer sensitivity up to an effective new physics mass scale of $\mathcal{O}(10^{4}$ TeV/c$^{2}$), going far beyond what can be achieved in direct, collider-based, searches. The theoretical motivation, designs and anticipated timelines for these three experiments are presented. These experiments are a crucial part of a global search for CLFV. Continued support for all planned experimental searches for muonic CLFV is strongly encouraged.
