Based on: 1906.04573[hep-ph]
Abstract: We propose to study the flavor properties of the top quark at the future Circular Electron Positron Collider (CEPC) in China. We systematically consider the full set of 56 real parameters that characterize the flavorchanging neutral interactions of the top quark, which can be tested at the CEPC by the single top production channel. Compared with current bounds from the LEP2 data and the projected limits at the high-luminosity LHC, we find that the CEPC could improve the limits on four-fermion flavor-changing coefficients by one to two orders of magnitude, and in the meantime providing similar ...
