Automated resummation of electroweak Sudakov logarithms in diboson production at future colliders

Abstract

Abstract At energies that are large with respect to the electroweak scale, the electroweak corrections to scattering processes involve large logarithms that have to be resummed to obtain decent predictions. Soft-collinear effective theory (SCET) has been proposed as a suitable framework to allow for this resummation, while retaining non-logarithmic corrections in a consistent way. In this paper, we investigate the approximations needed to use this approach for the calculation of electroweak corrections to off-shell diboson production at high-energy colliders. Upon implementing the method into a Monte-Carlo integration code, we provide resummed predictions for cross sections and distributions at a $$3\,\text {TeV} $$ 3 TeV lepton collider and a $$100\,\text {TeV} $$ 100 TeV proton collider.
