论文摘要
已经提出了Muone实验，以通过将CERN M2 Beam的160 GEV MUON与薄靶板的原子电子碰撞，以测量$μe弹性散射的差分横截面。从非常精确的测量来看，一个人可以实现对MUON磁矩的竞争性确定，而不是其他现有的磁矩。为了准备使用降低的设置进行测试运行，检测器几何形状已被优化。讨论了统计数据有限的第一次物理运行的预期收益率，以及评估主要系统不确定性的前景。
The MUonE experiment has been proposed to measure the differential cross section of $μe$ elastic scattering, by colliding the 160 GeV muons of the CERN M2 beam with atomic electrons of thin target plates. From a very precise measurement of the shape one can achieve a competitive determination of the leading hadronic contribution to the muon magnetic moment, independent from the other existing ones. In preparation for the Test Run with a reduced setup the detector geometry has been optimised. Expected yields for a first physics run with limited statistics are discussed, together with prospects for the assessment of the main systematic uncertainties.
