The Mu2e experiment looks for charged lepton flavour violation by looking for the neutrinoless conversion of a muon to an electron in the field of a nucleus. Lepton flavour violation has been observed in the neutral sector through neutrino oscillations but it has not yet been observed in the charged sector. The rate allowed in the Standard Model is well below the level that experiments can currently reach so any observation would be a sign of new physics. The experiment is currently under construction and aims to start commissioning in 2021. The project has a specific focus on installing and commissioning the stopping target monitor (one of the detectors being provided for the experiment by the UK) with involvement in writing both the DAQ and DQM as well as offline analysis code. There will also be data analysis both of test beam data taken before the installation into the experiment as well as analysis of the initial data taken by the experiment during the commissioning period.

Mu2e实验通过在原子核的场中寻找μ子到电子的无中微子转换来寻找带电轻子味违反。轻子味违反已被观察到在中性部门通过中微子振荡，但它尚未被观察到在带电部门。标准模型中允许的速率远低于目前实验所能达到的水平，因此任何观测都将是新物理学的标志。该实验目前正在建设中，计划于2021年开始试运行。该项目的具体重点是安装和调试停止目标监测器（英国为实验提供的探测器之一），并参与编写DAQ和DQM以及离线分析代码。还将对安装到实验中之前采集的测试梁数据以及调试期间实验采集的初始数据进行数据分析。
