Abstract:
Future circular electron-positron colliders such as CEPC and FCC-ee are versatile machines proposed to operate as Higgs, electroweak, flavor, and top quark factories. FCC-ee, for example, expects a production of 6 trillion Z bosons, 200 million W boson pairs, 2 million Higgs bosons, and 2 million top quark pairs with a clean experimental environment and well-determined center-of-mass energies. Such data would offer excellent opportunities in a broad physics program, some are unique or highly advantageous compared to other experiments. Selected highlights include precise measurements of the Higgs boson mass and width, Higgs decays to hadronic final states, ultra precise measurements of W boson and top quark masses, model-independent determination of CKM matrix elements, high precision tests in flavor physics, and direct probes to BSM signatures below the electroweak scale. This talk gives an overview of the broad physics program at FCC-ee and some projected results from recent studies.
About the speaker:
Xunwu got his bachelor's degree from the University of Science and Technology of China (USTC) in 2015, and his PhD from the University of Florida (UF) in 2021. He is currently a postdoctoral researcher at Karlsruhe Institute of Technology (KIT). His research topics include searches for rare decays of the Higgs boson and precise measurement of Standard Model processes at the Large Hadron Collider (LHC), as well as a wide range of physics case studies at the Future Circular Collider (FCC), spanning Higgs, top, flavor and BSM topics. He is currently serving as a convener of the “FCC Higgs and Top physics group”. He has also participated in the proposal and prospective studies of the Muon-Ion Collider (MuIC) concept.
