The project will focus on analysis of data samples from the LHCb experiment, to study the spectra of excited charm mesons and to search for tetra-quark states. The measurement will be the first analysis of B+ -> D-K+pi+ decays using the full LHCb data sample. The student will contribution to all stages of the measurement, from data processing and selection, through to a state-of-the-art amplitude analysis to fit for the different contributions of the B+ -> D-K+pi+ data sample. The project will also focus on studies of Low Gain Avalanche Detectors (LGADs), collaborating with the detector development group at the University of Glasgow. The LHCb vertex detector (VELO) must be upgraded in the future to allow the experiment to take advantage of the high luminosity LHC. LGADs are one possible sensor technology choice for the VELO in upgrade 2, but research and development, in particular around concerns of the radiation hardness are required to show that it is a viable option.

该项目将侧重于分析LHCb实验的数据样本，研究激发粲介子的光谱，并寻找四夸克态。该测量将是首次使用完整的LHC B数据样本分析B+ -> D-K+ π +衰变。学生将参与测量的所有阶段，从数据处理和选择，到最先进的振幅分析，以适应B+ -> D-K+pi+数据样本的不同贡献。该项目还将与格拉斯哥大学的探测器开发小组合作，重点研究低增益雪崩探测器。LHCb顶点探测器（VELO）必须在未来升级，以使实验能够利用LHC的高亮度。LGAD是VELO在升级2中的一种可能的传感器技术选择，但需要进行研究和开发，特别是围绕辐射硬度的研究和开发，以证明这是一个可行的选择。
