$ e^+ e^-\to\gamma\gamma$ at large angle for FCC-ee luminometry

We examine large-angle two photon production in e +e − annihilation as a possible process to monitor the luminosity of FCC-ee. We review the current status of the theoretical predictions and perform an exploratory phenomenological study of the next-to-leading and higher-order QED corrections using t...

description We examine large-angle two photon production in e +e − annihilation as a possible process to monitor the luminosity of FCC-ee. We review the current status of the theoretical predictions 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 consider the one-loop weak corrections, that are necessary to meet the high-precision requirements of FCC-ee. Possible ways to approach the target theoretical accuracy are sketched.
