Electroweak corrections to $e^{+}{e}^{-}\to \gamma \gamma$ as a luminosity process at FCC-ee

Carlo M. Carloni Calame, Mauro Chiesa, Guido Montagna +2

We consider large-angle two photon production in $e^{+}{e}^{-}$ annihilation as a possible process to monitor the luminosity of a future $e^{+}{e}^{-}$ circular collider (FCC-ee). We review…
