DESCRIPTION:Speakers: Haifeng Li (Shandong University)\nAbstract:\n\nThis
  talk will review the recent H → 𝜇𝜇 and toponium results from 
 the ATLAS experiment at the Large Hadron Collider. For H → 𝜇𝜇 sear
 ch\, an excess of events over the background is observed with a significan
 ce of 3.4σ. This result provides evidence for the H → 𝜇𝜇 decay w
 ith ATLAS data and offers a direct probe of the Higgs-boson Yukawa couplin
 g to second-generation fermions. For toponium search\, an excess of even
 ts is observed over the baseline perturbative QCD prediction with an obser
 ved significance of 8σ. This excess is consistent with the formation of 
 color-singlet\, S-wave\, quasi-bound t¯t states as predicted by non-re
 lativistic QCD.\n\nAbout the speaker:\n\n李海峰，山东大学前沿交
