Analysis of charm physics data with LHCb

该研究项目将对CERN LHCb实验收集的数据进行分析，以解决STFC的一些基本科学挑战：“为什么物质比反物质多？”物理学的基本定律和对称性是什么？'.这将通过测量粲强子和它们的反粒子伙伴的行为差异来完成，以研究它们的行为在将粒子交换为反粒子并镜像反应时是否保持不变。这被称为CP转换，该项目将测量在这种转换下反应的变化程度。该方法涉及使用机器学习算法来识别候选信号，计算机建模来描述衰变过程，以及先进的统计方法来提取感兴趣的物理参数。该项目将与LHCb合作的国际同事以及实验的主办机构CERN密切合作。

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.
