Deputy Director of the Institute of High Energy Physics, CAS, Prof. CAO Jun, delivered a welcome speech, providing an overview of IHEP development history, the construction and operation status of major scientific facilities as well as development plans of IHEP, and extended best wishes for the successful outcome of the conference. The conference featured 103 oral presentations, which extensively discussed the experimental and theoretical results of Higgs boson research in high-energy physics, including the latest measurements of Higgs boson properties and the latest theoretical developments in the field of Higgs bosons, the Standard Model, and physics beyond the Standard Model. In addition to the progress and upgrades of experiments at the Large Hadron Collider at CERN, discussions at the conference also covered the progress of next-generation Higgs factories, circular or linear electron-positron colliders, 100 TeV proton-proton colliders, as well as muon collider in various regions worldwide. Finally, after discussing several key issues and the future physics prospects of colliders, the conference concluded successfully.
