The optical theorem connects hadronic total cross sections to hadron elastic scattering amplitudes. In our work\, we calculate\, from first pr inciples\, the Euclidean correlation functions of Wilson loops that can be used to reconstruct high-energy meson-meson scattering amplitudes in a fu nctional-integral approach. Additionally\, considering the crossing symmet ry of the loop-loop correlation functions\, we clearly observe odderon exc hange in the high-energy soft interactions between two quark dipoles.\n\n 个人简介：\n\n梁剑，华南师范大学量子物质研究院研究 员，博士生导师。2010年本科毕业于南开大学，2015年于中 国科学院高能物理研究所获得博士学位，后在美国肯塔 基大学从事博士后研究。2020年入职华南师范大学，2022年 获得国家优秀青年基金资助。主要从事格点量子色动力 学相关的研究工作，致力于从第一性原理出发通过大规 模数值模拟研究强子结构与性质。\nhttps://indico.ihep.ac.cn/e vent/23533/ LOCATION:图书馆楼319 URL:https://indico.ihep.ac.cn/event/23533/ END:VEVENT END:VCALENDAR
