Abstract
We consider QCD radiative corrections to top-quark pair production at hadron colliders. We use the qT subtraction formalism to perform a fully differential computation for this process. Our calculation is accurate up to the next-to-leading order in QCD perturbation theory and it includes all the flavour off-diagonal partonic channels at the next-to-next-to-leading order. We present a comparison of our numerical results with those obtained with the publicly available numerical programs MCFM and Top++.| File | Dimensione | Formato | |
