Abstract:
This paper gives high-precision theoretical predictions for cross sections of the process $e^+e^- \to \gamma Z$ for future electron–positron colliders. The calculations are performed using the SANC system. They include complete one-loop electroweak radiative corrections, as well as longitudinal polarization of the initial state. Numerical results are given for the center-of-mass system energy range $\sqrt s = 250$–$1000$ GeV with various polarization degrees in the $\alpha(0)$ and $G_\mu$ EW schemes. This study is a contribution to the research program of the CEPC project being under development in China.
