论文摘要
寻找MUON的永久性电偶极矩（EDM）是对粒子物理标准模型以外的物理学的绝佳探针。我们提出了第一个专门的MUON EDM搜索，该搜索是在瑞士的Paul Scherrer Institute（PSI）中采用冷冻旋转技术的，其灵敏度为$ 6 \ times 10^{ - 23} 〜e \！ 震级。为了准备高精度实验以测量MUON EDM，在PSI上进行了几项研发研究：可能的梁线表征，以托管MUON束注射研究的实验，并测量了低矩材料在低矩材料中的多个库仑在效率下的库仑散射，以开发效力学材料。本文讨论了PSI上MUEDM实验的实验概念和当前状态。
The search for a permanent electric dipole moment (EDM) of the muon is an excellent probe for physics beyond the Standard Model of particle physics. We propose the first dedicated muon EDM search employing the frozen-spin technique at the Paul Scherrer Institute (PSI), Switzerland, with a sensitivity of $6 \times 10^{-23}~e\!\cdot\!\mathrm{cm}$, improving the current best limit set by the E821 experiment at Brookhaven National Laboratory by more than three orders of magnitude. In preparation for a high precision experiment to measure the muon EDM, several R&D studies have been performed at PSI: the characterisation of a possible beamline to host the experiment for the muon beam injection study and the measurement of the multiple Coulomb scattering of positrons in potential detector materials at low momenta for the positron tracking scheme development. This paper discusses experimental concepts and the current status of the muEDM experiment at PSI.
