- Abstract
We present the implementation of next-to-next-to-leading order (NNLO) QCD fully-differential corrections within the Geneva framework, for both colour-singlet and colour-singlet+jet processes at hadron colliders, by employing a nonlocal subtraction approach. In particular, we discuss the implementation details and the challenges that arise when utilizing a dynamical infrared cutoff parameter. Additionally, we combine the subtraction with the projection-to-Born method in order to include fiducial power corrections. As a test case, we provide predictions for Drell-Yan and Z+jet production at the LHC, using N-jettiness as resolution variable. We validate the NNLO corrections of Geneva against nnlojet finding excellent agreement. Finally, we discuss how to extend our method to calculate the N3LO QCD fully-differential corrections to colour-singlet production at hadron colliders.
