Comparison of ttW theory predictions in the 3 channel
Abstract
We report on our recent comparison of various theoretical approaches to predict fiducial signatures for pp ttW in the 3 decay channel at O(αs3α6) 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 and POWHEG-BOX frameworks.
