The precise measurements of the Standard Model (SM) Higgs boson and the searches for new physics are the most important tasks for High Energy Physics at the Large Hadron Collider (LHC). The ATLAS detector at LHC has good performances on the reconstruction and identification of photons, as a result, the di-photon final state is one of the most sensitive decay channels to measure the Standard Model Higgs boson properties. In this talk, I would like to introduce and discuss the different approaches of measuring Higgs boson properties in the H→γγ channel, or searching for new physics associated with the Higgs boson. I will highlight several important physics analyses using the full Run2 pp collision data at 13 TeV with the ATLAS experiment. In addition, I will discuss the physics analysis in the future and the upgrade of the ATLAS detector.
About the speaker:
Dr. Shuo Han is currently a postdoctoral researcher at the Lawrence Berkeley National Laboratory (LBNL). In the past 3 years, he was leading the Higgs property measurements in the diphoton final state with the ATLAS experiment, and has made important contributions to the search for new physics associated with the Higgs boson. He is also working on the ATLAS Phase-2 upgrade of the inner tracker strip detector at the LBNL site. Shuo Han obtained his Ph.D degree from the Institute of High Energy Physics, Chinese Academy of Science (IHEP) in 2019. His PhD thesis focused on the photon identification measurement with the ATLAS detector and the search for the Z boson plus photon decay of the Higgs boson. During 2017 to 2019, He was a visiting PhD student at the Deutsches Elektronen-Synchrotron (DESY). His current interests include the precise measurements of the Standard Model and the new physics searches at the Large Hadron Collider, the novel machine learning techniques with physics analysis, and the inner tracker strip detector.
