A mini-workshop on Low-Mass Multi-lepton Final States, co-hosted by Nanjing Normal University, Fudan University and Tsinghua University, was successfully held in Nanjing Normal University from June 19 to 20, 2020. More than 70 experts and scholars from Nanjing Normal University, Tsinghua University, Institute of High Energy Physics of the Chinese Academy of Sciences, Peking University, Fudan University, University of Science and Technology of China, Nankai University, Shandong University, Beihang University, Institute of theory of the Chinese Academy of Sciences and North China Electric Power University attended the workshop.
In line with the national epidemic protection policy, most experts attended this workshop via internet, and a few of them attended in person. Professor Yi Kai from Nanjing Normal University introduced the current situation and prospect of Low-Mass Multi-lepton Final States at the beginning of the meeting, which triggered a hot discussion. The seven theoretical reports covered the theoretical progresses on fully heavy-flavor multi-quark state predications from various aspects such as CLQCD, sum rules of QCD and effective field theory, as well as possible problems in various models.
Professor Zhao Guangda, an academician from Peking university commented that the research on low mass multi-leptons final states is one of the hot topics of present researches in the summary remarks, and this workshop promotes the collaboration between theoretical and experimental researches, which enables domestic scholars to make great contributions to high energy physics both experimentally and theoretically. In particularly, he hoped that the Chinese CMS group will have important results in the near future. Professor Li Xueqian of Nankai University believed that serious theoretical and experimental research work should be performed, and it could be another great innovative work contributed by Chinses LHC groups If new structures are discovered. It provides a good chance for young people to make significant contribution in this developing area.
This workshop will continue to promote the rapid development of particle physics research in our country, especially for the field of Exotic Hadrons. Details of the workshop can be found at: https://indico.ihep.ac.cn/event/11966/overview.
