Description of Bhabha-scattering at small angles using the Monte Carlo generator ReneSANCe

Abstract

Results of a simulation of Bhabha small-angle scattering process at center-of-mass energy of 240~GeV and at the $Z$-boson resonance using the Monte Carlo generator {\tt{ReneSANCe}} are presented. For the given accuracy about $10^{-4}$ in estimating luminosity of future electron-positron accelerators, the minimum cutoff angle for simulated events is established.
