The mu3e experiment searches for a rare flavour violating decay of the muon to three electrons. The decay is highly suppressed in the standard model and any observation of signal will be a herald of new physics. The experiment is currently under construction in the Paul-Scherrer Institute in Switzerland by an international collaboration and is scheduled to take its very first data in 2020. This PhD thesis will take place within the Liverpool mu3e group, which currently leads the UK participation in the experiment and mu3e tracker construction. The group also contributes to the development of the experiment software framework. The thesis topic will focus on the commissioning of the tracker towards the first data taking, the understanding of the mu3e detector performance and the analysis of the very first data. In addition to contributing to the very first results on the mu->3e decay, the student will explore the possibility of expanding the experiment's physics potential by developing and optimizing software for the GPU farm to select and analyse in real time mu->eeeX decays, where X is a new particle, e.g. a new neutral boson or a dark photon. The student will also have the opportunity to explore the interconnections of the sensitivity to these particles with results from other experiments in the lepton sector and the LHC.

μ 3e实验寻找一种罕见的味道，它破坏了μ介子衰变为三个电子的过程。衰变在标准模型中被高度抑制，任何信号的观测都将是新物理学的先驱。该实验目前正在瑞士Paul-Scherrer研究所进行国际合作，计划于2020年获得第一批数据。这篇博士论文将在利物浦mu 3e小组内进行，该小组目前领导英国参与实验和mu 3e跟踪器建设。该小组还为实验软件框架的开发做出了贡献。本论文的主题将集中在第一次数据采集的跟踪器的调试，mu 3e探测器性能的理解和第一次数据的分析。除了对mu->3e衰变的第一个结果做出贡献外，学生还将探索通过开发和优化GPU场的软件来扩展实验物理潜力的可能性，以在真实的时间内选择和分析mu->eeeX衰变，其中X是新粒子，例如新的中性玻色子或暗光子。学生还将有机会探索这些粒子的敏感性与轻子部门和LHC其他实验结果的相互联系。
