Electroweak radiative corrections to triple photon production at the ILC

Abstract

In this paper, we present the precision predictions for three photon production in the standard model (SM) at the ILC including the full next-to-leading (NLO) electroweak (EW) corrections, high order initial state radiation (h.o.ISR) contributions and beamstrahlung effects. We present the LO and the NLO EW+h.o.ISR+beamstrahlung corrected total cross sections for various colliding energy when $\sqrt{s}\ge 200\mathrm{GeV}$ and the kinematic distributions of final photons with $\sqrt{s}=500\mathrm{GeV}$ at ILC, and find that the NLO EW corrections, the h.o.ISR contributions and the beamstrahlung effects are important in exploring the process $e^{+}{e}^{-}\to \gamma \gamma \gamma$.
