Abstract:
The precise measurements of the Standard Model (SM) Higgs boson and the searches for new physics are the most important tasks at the Large Hadron Collider (LHC). The ATLAS detector has very good performances on the identification and energy reconstruction of photons, as a result, the di-photon final state is one of the most sensitive decay channels to measure a SM-like Higgs boson. In this presentation, I would like to introduce the specialness of the diphoton channel and discuss the different approaches of measuring Higgs boson property or searching for new physics with the diphoton final state. I will highlight two important physics analyses at 13 TeV using the full Run2 pp collision data collected by the ATLAS experiment at LHC. In addition, I will discuss the physics analysis in the future with the upgrade of the ATLAS detector.
Resume:
Dr. Shuo Han is currently a postdoctoral researcher at the Lawrence Berkeley National Laboratory (LBNL). In the past 2 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 displaced photons produced in Higgs exotic decays. He is also playing an essential role in 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.
