 stract:\n\nThirteen years after the discovery of the Higgs boson\, the LH
 C program has entered a precision era in exploring this remarkable particl
 e and its interactions. Among them\, the Higgs–vector-boson coupling off
 ers one of the cleanest and most powerful windows onto physics beyond the 
 Standard Model. Tiny deviations in this interaction could reveal new pheno
 mena\, including charge–parity (CP) violation in the Higgs sector. Such 
 CP violation is not only a compelling target for collider measurements\, b
 ut also an essential ingredient in our broader quest to understand the mat
 ter–antimatter asymmetry of the Universe.In this seminar\, I will intr
 oduce how Effective Field Theory provides a systematic framework for searc
 hing for CP-violating Higgs interactions. I will then discuss recent exper
 imental and theoretical developments that have sharpened the precision of 
 Higgs measurements\, with a focus on analyses using the full Run-2 proton-
 proton collision dataset collected by the ATLAS detector at a center-of-ma
 ss energy of 13 TeV.\n\nAbout the speaker：\nJiayi Chen  received her 
 Ph.D. in Physics from Brandeis University in the United States and is curr
 ently a postdoctoral researcher at Simon Fraser University in Canada. She 
 primarily participates in precision measurements of the Higgs boson in the
  ATLAS experiment. ATLAS is one of the large-scale high-energy particle ph
 ysics experiments at the Large Hadron Collider (LHC) at CERN. Her research
  focuses on the HWW decay channel\, Vector Boson Fusion production mechani
 sms\, interpretations using Effective Field Theory\, and studies of Higgs 
 CP properties. During her Ph.D. and postdoctoral years\, she has been acti
 vely involved in ATLAS Higgs physics analyses and has also contributed to 
 the upgrade of the ATLAS Inner Tracker (ITk) silicon microstrip detector f
 or the High-Luminosity LHC (HL-LHC) phase.\n\n \nhttps://indico.ihep.ac.c
