Abstract:
Perturbative cross-sections in QCD are plagued by kinematic divergences. While UV divergences are systematically handled through coupling and field renormalization, IR divergences - arising from soft and/or collinear partons - can be treated in multiple ways. One approach is the construction of a local subtraction scheme. In this talk, we present the extension of the CoLoRFulNNLO subtraction scheme to hadron-hadron collisions, focusing on the analytic computation of the integrated subtraction terms for the production of a color-singlet final state to NNLO accuracy.
