Abstract:
With the full Run 2 pp collision dataset collected at 13 TeV, very detailed measurements of Higgs boson coupling properties can be performed using a variety of final states, identifying several production modes and its decays into bosons and fermions, and probing different regions of the phase space with increasing precision. These measurements have been combined to exploit the strength of each channel, thus providing the most stringent global measurement of the Higgs coupling properties. The Higgs boson self-coupling can be further constrained by exploiting higher-order electroweak corrections to single Higgs boson production. This talk presents the latest combination of Higgs boson coupling measurements by the ATLAS experiment, discussing results in terms of production modes, branching fractions, as well as their interpretations in the framework of kappa modifiers to the strength of the various coupling properties, including the Higgs self-coupling.
Speaker:
Dr. Zirui Wang is currently a postdoctoral fellow at the University of Michigan, Ann Arbor. He obtained both bachelor’s degree (2014) and doctor’s degree (2019) at Shanghai Jiao Tong University. His thesis work is on the measurements of the Higgs boson properties in the diphoton decay channel, and in the combination of all available Higgs production modes and decay channels with ATLAS 13 TeV proton collision data collected during the LHC Run 2 operation. His research focuses on the ATLAS experiment at the Large Hadron Collider, involving Higgs measurements and dark matter searches with collider signatures. His wider contributions include significant roles in the ATLAS muon system operations and upgrades.
