报告人介绍

Dr. Rui Zhang is working with the ATLAS experiment in the University of Wisconsin-Madison, US. He obtained his Ph.D in the University of Bonn, Germany, with the research on the single top quark production at ATLAS. He had worked in the BESIII collaboration in the UCAS on the topic of a charm quark FCNC decay for the Master degree, and studied in Tianjin University for his Bachelor’s degree. His current interest includes di-higgs searches, top quark measurements, anomaly detection, machine learning of both classical and quantum.

报告摘要

The discovery and properties measurements of the Higgs boson provide a deep understanding of the mechanism of electroweak symmetry breaking. However, the exact shape of the Brout, Englert and Higgs (BEH) potential remains unprobed. One of the parameters that determines its form is the Higgs boson’s trilinear self-coupling that can be measured via Higgs-boson pair (HH) production. Such HH production in SM more than 1000 times rarer than single Higgs-boson production, making it challenging to measure.

Various searches in different Higgs decay products are being conducted at ATLAS using the Run 2 data. The 4b final states, where both Higgs decays to two b-jets, will be discussed. A combination of various decay channels will be presented and these latest results inspire confidence that the observation of the SM HH production and a precise measurement of the Higgs-boson trilinear self-coupling may be possible at the HL-LHC.
