Heavy flavour spectroscopy at LHCb

该项目将专注于分析LHCb实验的数据样本，研究激发的Charm介子的光谱，并寻找四夸克态。这项测量将是第一次使用完整的LHCb数据样本对B+-&gt；D-K+pi+衰变进行分析。学生将对测量的所有阶段做出贡献，从数据处理和选择，到最先进的幅度分析，以适应B+-&&gt；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(LGAD)。LHCb顶点探测器(VELO)必须在未来进行升级，以使实验能够利用高亮度的LHC。在升级2中，LGAD是VELO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考虑，以证明这是一个可行的选择。

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.
