One-loop Electroweak and QCD corrections to vector boson scattering into top pairs and application to ILC

TL;DR

This paper computes electroweak and QCD corrections to vector boson scattering into top pairs, providing predictions for high-energy e+e- colliders and analyzing the impact of anomalous interactions on these processes.

Contribution

It presents the first detailed calculation of electroweak and QCD corrections to VV -> tt processes and their integration into collider predictions considering anomalous couplings.

Findings

Electroweak and QCD corrections significantly affect VV -> tt cross sections.

Anomalous interactions modify the scattering amplitudes and observable distributions.

Predictions are made for future high-energy e+e- collider experiments.

Abstract

We calculate the electroweak and QCD corrections to W-W+ -> tt and ZZ -> tt. We also consider the interplay of these corrections with the effect of anomalous interactions that affect the massive weak bosons and the top. The results at the VV level fusion are convoluted with the help of the effective vector boson approximation to give predictions for a high energy e+e- collider.
