摘要:

MUonE 实验旨在通过将 CERN M2 束流的 160 GeV μ 子与薄靶板的原子电子碰撞,测量 μe 弹性散射的微分截面。通过精确测量其形状,可以独立于其他现有方法,竞争性地测定 μ 子磁矩的主导强子贡献。在准备使用精简装置的测试运行期间,探测器几何结构已得到优化。本文讨论了统计量有限的首次物理运行的预期产额,以及评估主要系统不确定性的前景。

英文摘要:

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.
