摘要(Abstract)：

底介子谱学的研究是高能物理中重要的研究课题之一。由于重夸克质量和寿命上的特殊，重味系统中往往会出现特殊的现象。底介子作为开放味强子，呈现出丰富的谱学结构。研究底介子谱学，为深入理解强相互作用的束缚本质提供关键信息。LHCb作为大型强子对撞机（LHC）上唯一针对重味物理而优化的实验，致力于通过研究重味强子的稀有衰变和CP破坏来间接寻找超出粒子物理标准模型的新物理，同时也是研究底强子谱学的优秀平台。在过去十几年里，LHCb实验开展了多项底介子谱学研究，报道了多个底介子激发态的首次发现，并将已知底介子性质的测量精度提升至新水平。伴随着LHCb第一次大型升级的结束和运行三期结束临近，本文综合性的总结介绍了LHCb实验多年来在底介子谱学方面的进展，并进一步展望了未来LHCb的技术升级将为底介子谱学研究带来的前景。
