Based on the pNRQCD formalism\, we obtain expressions for the LDMEs in terms of the quarkonium wavefunctions at the origin and universal gluonic correlat ors\, which do not depend on the heavy quark flavor or the radial excitati on. This greatly reduces the number of nonperturbative unknowns and substa ntially enhances the predictive power of the nonrelativistic effective fie ld theory formalism. We obtain improved determinations of the LDMEs for J/ ψ\, ψ(2S)\, and Υ states thanks to the universality of the gluonic corr elators\, and obtain phenomenological results for cross sections and polar izations at large transverse momentum that agree well with measurements at the LHC.\n\n王翔鹏，2011年本科毕业于吉林大学，2014年硕 士毕业于中科院大学，2018年博士毕业于德国汉堡大学和 德国同步辐射加速器中心 (DESY)。在美国阿贡国家实验室 做完第一期博后之后，目前在德国慕尼黑工业大学做第 二期博后。研究方向主要为重夸克偶素物理，微扰QCD高 阶计算，有效场论及QCD因子化。\n\n \n\nTime: 2:00 pm Friday\, Feb 17\, 2023\n\nLocation: 江湾物理楼 C101 \n\n腾讯会议 ID: 20 4 363 728 Passcode: 200438\n\nHost: Dingyu Shao\n\n \n\n点击 链接入会，或添加至会议列表：\nhttps://meeting.tencent.com/dm /AMwVudkxT5xd\n\n#腾讯会议：204-363-728\n会议密码：200438\n\n \ nhttps://indico.ihep.ac.cn/event/18972/ URL:https://indico.ihep.ac.cn/event/18972/ END:VEVENT END:VCALENDAR
