内容摘要： The Higgs factory is regarded as the highest-priority future collider experiment, as it could provide decisive data on our exploration to multiple profound mysteries, including the origin of mass, origin of matter, nature of dark matter, etc. Take the Circular Electron Positron Collider as an example, it is expected to deliver 4 million Higgs bosons, hundreds of Millions of W bosons, 4 Tera Z bosons, and potentially also 1 million top quarks in an extremely clean collision environment. The CEPC could well be the gateway towards the profound physics principles, by hundreds of promising observations though not only the precise Higgs measurements, but also Electroweak, Flavor physics measurements and direct New Physics signal hunting.The extremely rich physics program at the CEPC poses stringent requirements on the detector performance, which could be addressed by the state-of-the-art detector design, detector technology, meanwhile, the AI technology could further and strongly boost the discovery power of the Higgs factory. This talk presents several corner stones of the AI enhanced reconstruction and analysis methods at the CEPC, including the Holistic approach that could significantly boost the performance of different jets identification and the signal-background separation, the Color Singlet identification which is critical for the physics measurements with full hadronic events, and the Particle Flow that pursues the 1-1 correspondence between reconstructed particle and final state particles.

Being a researcher at the Institute of High Energy Physics, Chinese Academy of Science, I focus on the physics and detector studies for the Circular Electron Positron Collider (CEPC), a proposed gigantic future Higgs/Z factory. I am responsible for the CEPC physics potential analysis, the detector design - optimization, and the reconstruction algorithm/software development.
