论文摘要
A high-statistics determination of the differential cross section of elastic muon-electron scattering as a function of the transferred four-momentum squared, $d σ_{el}(μe \to μe)/dq^2$, has been argued to provide an effective constraint to the hadronic contribution to the running of the fine-structure constant, $Δα_{had}$, a crucial input for precise理论预测若子的异常磁矩。为此，正在CERN北区计划进行一个名为``Muone''的实验。我们考虑了Muone协作提出的检测器的几何形状，并基于对弹性Muon-Electrons散射事件的快速模拟以及对检测器几何形式的许多可能的塑造的研究，提供了有关被动目标材料布局和硅脱带传感器的放置的一些建议。
A high-statistics determination of the differential cross section of elastic muon-electron scattering as a function of the transferred four-momentum squared, $d σ_{el}(μe \to μe)/dq^2$, has been argued to provide an effective constraint to the hadronic contribution to the running of the fine-structure constant, $Δα_{had}$, a crucial input for precise theoretical predictions of the anomalous magnetic moment of the muon. An experiment called ``MUonE'' is being planned at the north area of CERN for that purpose. We consider the geometry of the detector proposed by the MUonE collaboration and offer a few suggestions on the layout of the passive target material and on the placement of silicon strip sensors, based on a fast simulation of elastic muon-electron scattering events and the investigation of a number of possible solutions for the detector geometry.
