DESCRIPTION:Speakers: Haifeng Li（李海峰） (Shandong University)\n\nA
 bstract：This talk will review the recent H → 𝜇𝜇 and toponium re
 sults from the ATLAS experiment at the Large Hadron Collider. For H → 
 𝜇𝜇 search\, an excess of events over the background is observed with
  a significance of 3.4σ. This result provides evidence for the H → 
 𝜇𝜇 decay with ATLAS data and offers a direct probe of the Higgs-boso
 n Yukawa coupling to second-generation fermions. For toponium search\, an 
 excess of events is observed over the baseline perturbative QCD prediction
  with an observed significance of 8σ. This excess is consistent with the
  formation of color-singlet\, S-wave\, quasi-bound t¯t states as predict
 ed by non-relativistic QCD.Biography：Dr. Haifeng Li is a Professor at th
 e Institute of Frontier and Interdisciplinary Science\, Shandong Universit
 y\, Qingdao. He received his bachelor’s degree from Shandong University
  in 2005. From 2008 to 2012\, he conducted research on the ATLAS experimen
 t at the University of Wisconsin–Madison as a jointly supervised doctora
 l student. He obtained his Ph.D from Shandong University in 2012. From 201
 2 to 2017\, he carried out postdoctoral research at State University of Ne
 w York at Stony Brook. He joined Shandong University as a faculty in Septe
 mber 2017. Main research interests and achievements: During the discovery 
 of the Higgs boson (2011–2012)\, he was one of the key analyzers for the
  Higgs to WW channel\; he was one of the pioneers of the Higgs to dimuon s
 earch and once served as contact of the analysis team\; he has conducted r
 esearch on toponium.Alternative online link: https://meeting.tencent.com/d
