Prof. Changzheng YUAN (IHEP, Beijing)

Description

报告人:苑长征 研究员(高能所) 报告时间:2020年7月22日 15:00 – 16:30 摘要: Besides the peaks observed in inclusive hadronic cross section in e+e- annihilation, a few Y structures, Y(4260), Y(4360), Y(4660), are observed in exclusive hadronic cross sections in the charmonium energy region. In this talk, some new experimental results from BESIII experiment will be presented together with relevant results in bottomonium and other energy regions. Theoretical efforts are called for to understand the nature of these vector structures. 报告人简介: 1991年获华东师范大学物理学学士学位 , 1997年获中国科学院高能物理研究所博士学位 , 1997年至1999年中国高等科学技术中心,博士后 ; 1999年至2001年法国科研中心核物理与粒子物理研究所直线加速器实验室(LAL,IN2P3-CNRS), 博士后 ; 2001年起,中国科学院高能物理研究所,研究员。 现任BESIII合作组发言人。 参加北京谱仪(BES、BESIII)和Belle、Belle II实验, 带领研究团 队发现了带电类粲偶素Zc(3900)、Zc(4020)和 矢量类粲偶素Y(4660)等。 在国际核心刊物上发表 论文多篇。(参见SLACInspire数据库 http://inspirehep.net/author/profile/Chang.Zheng.Yuan.1 )
