Abstract

We examine large-angle two-photon production in e+e− annihilation as a possible process to monitor the luminosity of the FCC-ee. We review the current status of the theoretical pre- dictions and perform an exploratory phenomenological study of the next-to-leading and higher- order QED corrections using the Monte Carlo event generator BabaYaga@NLO. We also con- sider the one-loop weak corrections, which are necessary to meet the high-precision requirements of the FCC-ee. Possible ways to approach the target theoretical accuracy are sketched.
