NLO QED contributions to top-pair production at hadron collider

Abstract

Electroweak one-loop calculations for production of top-quark pairs at colliders are completed by providing the missing QED type contributions from real and virtual photons, where also effects from interference between QED and QCD contributions have to be taken into account. Moreover, photon-induced $t\bar{t}$ production is included as another partonic channel.
