e+e-γ production at photon-photon colliders at complete electroweak NLO accuracy

We present the NLO electroweak radiative corrections to the e(+)e(-)gamma production in gamma gamma collision, which is an ideal channel for calibrating the beam luminosity of a Photon Linear Collider. We analyze the dependence of the total cross section on the beam colliding energy, and then investigate the kinematic distributions of final particles at various initial photon beam polarizations at EW NLO accuracy. The numerical results indicate that the EW relative corrections to the total cross section are non-negligible and become increasingly significant as the increase of the beam colliding energy, even can exceed -10% in the J = 2 gamma gamma collision at root(s) over cap = 1 TeV. Such EW corrections are very important and should be taken into consideration in precision theoretical and experimental studies at high-energy gamma gamma colliders.

Automated summary

This study presents the NLO electroweak radiative corrections to e(+)e(-)gamma production in gamma gamma collision. The results show that these electroweak corrections have a significant impact on the total cross section, becoming more important with increasing collision energy.
