DESCRIPTION:Speakers: Shan JIN（金山） (Nanjing University)\n\nAbstrac
 t:\nThis talk introduces the concept of glueballs\, their significances\, 
 and their expected experimental signatures\, followed by a brief review of
  the history and longstanding challenges of glueball searches. The main fo
 cus is on the discovery and investigation of X(2370) at BESIII\, with part
 icular emphasis on the latest experimental results. By comprehensive exami
 nation on all measured production and decay properties of X(2370) at BESII
 I with the expected properties of a glueball and all other possible interp
 retations\, it is found that the observed properties of X(2370) are fully 
 consistent with expectations for the lightest 0⁻⁺ glueball\, while oth
 er interpretations can hardly explain all these properties simultaneously.
  The existence of a 0⁻⁺ glueball is therefore essential for a natural 
 and complete explanation of the properties of X(2370) observed by BESIII. 
 The conclusion is that the lightest 0⁻⁺ glueball is the dominant const
 ituent of X(2370).\nBiography:\nShan JIN is a professor at Nanjing Univers
 ity. He became a professor at the Institute of High Energy Physics\, Chine
 se Academy of Sciences (IHEP\, CAS)\, in 2001\, and was appointed a Distin
 guished Professor at Nanjing University in 2017. He was selected for the C
 AS Hundred Talents Program in 2001 and received support from the National 
 Science Fund for Distinguished Young Scholars in 2004. In 2014\, he was se
 lected among the first group of Leading Talents under China’s National 
 “Ten Thousand Talents Program.”\nIn 2013\, he received the Second Priz
 e of the State Natural Science Award of China\, for the discovery of X(183
 5)\, the first new particle discovered at the Beijing Electron-Positron Co
 llider. In 2011\, due to the discovery of the X(2370) new particle at BESI
 II\, he received the Outstanding Supervisor Award of the Chinese Academy o
 f Sciences.\nHe also served for many years as the Team Leader of the ATLAS
  Chinese Cluster at the Large Hadron Collider and made important direct co
 ntributions to the discovery of the Higgs boson by the ATLAS experiment in
  2012. As Chief Scientist of the National Key Research and Development Pro
 gram project “Physics Analysis of ATLAS Run-2 Data\,” he made sustaine
 d and key contributions to two achievements selected by Physics magazine o
 f the American Physical Society among its annual Top Ten Physics Highlight
 s: the 2018 observation of the coupling between the Higgs boson and heavy 
 quarks\, and the 2022 advances in measurements of Higgs-boson properties. 
 He shared the 2025 Breakthrough Prize in Fundamental Physics.\nAlternative
