Analysis of charm physics data with LHCb

这项研究项目将对欧洲核子研究中心LHCb实验收集的数据进行分析，以解决STFC的一些基础科学挑战：为什么物质比反物质多？以及“什么是物理学的基本定律和对称性？”这将通过测量魔法强子及其反粒子伙伴的行为差异来完成，以调查当将粒子交换为反粒子并反映反应时，它们的行为是否保持不变。这被称为CP转换，该项目将测量在此转换下反应变化的程度。该方法包括使用机器学习算法来识别候选信号，使用计算机建模来描述衰减过程，以及使用先进的统计方法来提取感兴趣的物理参数。该项目将与LHCB协作中的国际同事以及作为实验主办机构的欧洲核子研究中心密切合作完成。

This research project will perform analysis of data collected by the LHCb Experiment at CERN, to address a some of STFC's fundamental science challenges: 'Why is there more matter than antimatter?' and 'What are the fundamental laws and symmetries of physics?'. This will be done by measuring the difference in behaviour of charmed hadrons and their anti-particle partners, to investigate if their behaviour remains the same when exchanging particles to anti-particles and mirroring the reaction. This is called a CP transformation and the project will measure to what extent the reactions change under this transformation. The methodology involves using machine learning algorithms to identify signal candidates, computer modelling to describe the decay processes and advanced statistical methods to extract the physics parameters of interest. The project will be done in close collaboration with international colleagues in the LHCb collaboration and at CERN, which is the host institute of the experiment.
