Title: Higgs and Neutrinos: Portal to the Future of Particle Physics
Abstract: After the discovery of Higgs, the Standard Model (SM) is basically completed and particle physics is now at a turning point. On the one hand, SM is just an effective theory at current energy scale with a number of questions not yet answered. On the other hand, experimental evidence beyond the SM have been observed. It is commonly believed that a further understanding of physics at higher energies or deeper levels is needed, to be guided by more experimental discoveries. For such a purpose, Higgs and Neutrinos are the two main portals. I will describe our efforts along these two directions. One is based on the Jiangmen Underground Neutrino Observatory (JUNO) which will start the data taking soon. Another one is the Circular Electron-Positron Collider (CEPC) with a circumference of 100km. After 12 years efforts, CEPC is almost ready for construction. I will describe its design, R&D and the construction planning.
About the Speaker: Yifang Wang is known for his leading role (with Kam-Biu Luk) at Daya Bay Reactor Neutrino Experiment (the largest science collaboration project between US DOE and China) to determine the last unknown neutrino mixing angle θ. He is currently the PI for JUNO experiment aiming to determine the neutrino mass ordering and CP violations in the lepton sector. He is also leading the push for a future China Electron-Positron Collider. He shared with Kam-Biu Luk 2014 Panofsky Prize of APS, 2016 Breakthrough Prize in Fundamental Physics, and 2019 Future Science Prize. He has been elected as a Foreign associates of the National Academy of Sciences in 2024. Dr. Wang was the director of Institute for High-Energy Physics (2011-2024), Chinese Academy of Sciences.
