Precise Predictions for the Associated Production of a Boson with a Top-Antitop Quark Pair at the LHC Open
The production of a top-antitop quark pair in association with a W boson (tt¯W) is one of the heaviest signatures currently probed at the Large Hadron Collider. Since the first observation reported in 2015, the corresponding rates have bee…
