摘要

{Paul Scherrer研究所(PSI)的MUSE实验是旨在解决质子半径难题的一系列实验的一部分。MUSE特别有趣,因为它试图通过同时测量介子-质子散射和电子-质子散射来确定质子半径,此外还测量了这些带有正负轻子的反应。这不仅减少了系统的不确定性,而且还提供了对双光子交换贡献的灵敏度,这可能是早期实验中看到的一些差异的原因。MUSE几乎已经完成了调试阶段,并计划在今年秋天开始数据收集。我们报告了MUSE实验的现状和计划。

The MUSE experiment at PSI: Status and Plans
{The MUSE experiment at the Paul Scherrer Institut (PSI) is part of a suite of experiments that aim to resolve the proton radius puzzle. MUSE is particularly interesting because it attempts to determine the proton radius through simultaneous measurements of muon-proton scattering and electron-proton scattering, in addition to measuring these reactions with both positive and negative leptons. This not only reduces systematic uncertainties but also provides sensitivity to two-photon exchange contributions which may be responsible for some of the discrepancies seen in earlier experiments. MUSE has almost completed its commissioning phase and is scheduled to start data collection this fall. We report on the current status and plans of the MUSE experiment.
