Abstract
The production of a top-antitop quark pair in association with a W boson (t¯tW) is one of the heaviest signatures currently probed at the Large Hadron Collider. Since the first observation reported in 2015, the corresponding rates have been found to be consistently higher than the standard model predictions, which are based on next-to-leading order calculations in the QCD and electroweak interactions. We present the first next-to-next-to-leading order QCD computation of t¯tW production at hadron colliders. The calculation is exact, ex
