Projection-to-Born-improved Subtractions at NNLO
John Campbell, Tobias Neumann, Gherardo Vita
While the current frontier in fixed-order precision for collider observables is NLO, important steps are necessary to consolidate NNLO cross-section predictions with improved s…
Third order QCD predictions for fiducial W-boson production
