Over the past few years\, the CLQCD Collaboration has generated a series of gauge ensembles covering a wide range of lattice spacings\, volumes\, and quark masses\, enabling precision calculations with systematically con trolled uncertainties. In this talk\, I will present recent progress in st udies of hadron scattering using these ensembles.The talk is organized int o four parts. First\, for meson-meson scattering\, I will report precise d eterminations of the masses and widths of the ρ and K* resonances\, and d iscuss the pion-mass dependence of the D*(2300). Second\, in the meson–b aryon sector\, I will present studies of the scattering of doubly charmed baryons with light pseudoscalar mesons. These calculations aim to investig ate the spectrum of doubly charmed baryons and explore the possible existe nce of doubly charmed pentaquark states. Third\, I will discuss baryon–b aryon scattering\, with a focus on the nucleon–nucleon system. Finally\, I will present studies of three-body scattering\, including the isoscalar three-pion channel associated with the ω(782)resonance and the isovector three-pion channel relevant to the π(1300). Together\, these studies ill ustrate the expanding reach of lattice QCD in determining multihadron dyna mics and resonance properties directly from the underlying theory of stron g interactions.个人简介：刘柳明，中国科学院近代物理研 究所研究员。2002 年本科毕业于武汉大学， 2005年硕士毕 业于北京大学，2010年于美国威廉玛丽学院获得博士学位 。2010年—2017年先后在爱尔兰都柏林圣三一学院和德国波 恩大学从事博士后研究工作。2017 年 12 月开始在中国科 学院近代物理研究所任研究员。研究领域为格点量子色 动力学，研究工作主要集中在用格点量子色动力学的方 法研究强子谱与强子结构。 \n\nhttps://indico.ihep.ac.cn/even t/30566/ LOCATION:图书馆楼319 URL:https://indico.ihep.ac.cn/event/30566/ END:VEVENT END:VCALENDAR
