Measuring high-precision luminosity at the CEPC

Abstract Purpose Luminosity measurement at the Circular Electron-Positron Collider (CEPC) is required to achieve $$10^{-4}$$ 10 - 4 precision when operating at the center-of-mass energy of the Z-pole. Approximately 10 $$^12 $$ 1 2 Z-bosons will be collected to refine measurements...
