The doctoral student will perform searches for new physics in events with leptons and missing transverse momentum. Such searches are sensitive to models of new physics such as supersymmetry. Many such models contain long-lived invisible particles with masses in the 100s GeV range to which the analysis will be sensitive. The research therefore offers the potential to gain insight into the Dark Matter which appears to make up most of the matter content of the universe. The student will also undertake studies of the ATLAS high-level trigger algorithms with a view both to understanding features in the 2017-2018 data, and to improving the robustness of those algorithms against the additional "pileup" interactions which become increasingly numerous as LHC luminosity increases.

博士生将在具有轻子和缺少横向动量的事件中寻找新的物理学。这种搜索对超对称等新物理模型很敏感。许多这样的模型包含了长寿命的不可见粒子，其质量在100 GeV范围内，分析将对其敏感。因此，这项研究为深入了解暗物质提供了可能，暗物质似乎构成了宇宙的大部分物质。该学生还将进行ATLAS高级触发算法的研究，以了解2017-2018年数据的特征，并提高这些算法对额外的“堆积”相互作用的鲁棒性，这些相互作用随着LHC亮度的增加而变得越来越多。
