Exotic particle searches with ATLAS Run 3 data and preparing tracking software for High Luminosity LHC

该项目是使用ATLAS探测器在大型强子对撞机上搜索RUN 3质子-质子碰撞数据中的新物理信号。在低不变质量下偏离标准模型预期可能意味着新的/奇异的物理，例如暗光子的存在或高不变质量下新规范玻色子的存在，如Z‘或引力子。在第三次运行后，LHC将升级为高亮度大型强子对撞机。这将需要对ATLAS探测器进行重大升级，包括新的全硅内跟踪探测器(ITK)。作为ACTS项目的一部分，ATLAS航迹重建软件正在用改进的算法和现代软件工程实践进行重写，以充分利用新的探测器和新兴的计算架构。这项工作包括为ITK开发新的轨道重建软件，以及进行分析以寻找新的物理。

This project is to search for new physics signals in the Run 3 proton-proton collision data at the Large Hadron Collider using the ATLAS detector. Deviations from the Standard Model expectations at low invariant mass could indicate new/exotic physics, for example the existence of dark photons or at high invariant mass, new gauge bosons such as the Z' or graviton.After Run 3, the LHC will be upgraded to the High-Luminosity LHC. This will require a major upgrade of the ATLAS detector, including a new all-silicon inner tracking detector (ITk). As part of the ACTS project, the ATLAS track reconstruction software is being rewritten with improved algorithms and modern software engineering practices to take full advantage of the new detector and emerging computing architectures. The studentship includes developing new track reconstruction software for the ITk, as well as performing an analysis to search for new physics.
