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

本项目是利用ATLAS探测器在大型强子对撞机Run 3质子-质子碰撞数据中寻找新的物理信号。在低不变质量下，偏离标准模型的期望可能表明新的或奇异的物理现象，例如暗光子的存在，或者在高不变质量下，新的规范玻色子，如Z'或引力子。运行3后，LHC将升级为高亮度LHC。这将需要ATLAS探测器的重大升级，包括一个新的全硅内部跟踪探测器（ITk）。作为ACTS项目的一部分，ATLAS轨道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。该项目包括为ITk开发新的轨道重建软件，以及进行分析以寻找新的物理现象。

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.
