Abstract
We report on our recent comparison of various theoretical approaches to predict
fiducial signatures for pp→tˉtW in the 3ℓ decay channel at
O(α3sα6) and O(αsα8). The
comparison includes fixed-order predictions including full off-shell effects as
well as predictions based only on the double-resonant contributions by
employing the Narrow-Width-Approximation. Furthermore, we include parton-shower
matched predictions using the MG5_aMC@NLO and POWHEG-BOX frameworks.
