Description
One of the main obstacles to the calculation of next-to-next-to-leading order (NNLO) corrections in QCD is the presence of infrared singularities. Together with Raoul Röntsch, Kirill Melnikov and other collaborators, I am developing a more general approach to the nested soft-collinear subtraction method to address this problem for the production of an arbitrary final state at hadron colliders. In this presentation, I will discuss results for the process $P+P \to V + n$ gluons at NNLO, demonstrating the analytic cancellation of poles and presenting finite remainders of integrated subtraction terms, and will outline how the method can be completely generalized.
