Flavor Physics at the CEPC: a General Perspective
Xiaocong Ai, Wolfgang Altmannshofer, Peter Athron +147
We discuss the landscape of flavor physics at the Circular Electron-Positron Collider (CEPC), based on the nominal luminosity outlined in its Technical Design Report. The CEPC is d…
Verifying the Resonance Schemes of Unstable Particles at Lepton Colliders
Shao-Feng Ge, Ui Min, Zhuoni Qian
We propose practical ways of differentiating the various (Breit-Wigner, theoretical, and energy-dependent) resonance schemes of unstable particles at lepton colliders. First, the e…
New Physics Off the -Pole: at Future Lepton Colliders
Shao-Feng Ge, Zhuoni Qian, Michael J. Ramsey-Musolf +1
We explore the prospects for probing new physics (NP) beyond the Standard Model (SM) at future lepton colliders through precision measurements of observables…
The quark flavor-violating ALPs in light of B mesons and hadron colliders
Tong Li, Zhuoni Qian, Michael A. Schmidt +1
The axion-like particle (ALP) may induce flavor-changing neutral currents (FCNCs) when their Peccei-Quinn charges are not generation universal. The search for flavor-violating ALP…
