Regular Article- Theoretical Physics Automated NNLL + NLO resummation for jet-veto cross sections

Abstract In electroweak-boson production processes with a jet veto, higher-order corrections are enhanced by loga-rithms of the veto scale over the invariant mass of the boson system. In this paper, we resum these Sudakov logarithms at next-to-next-to-leading logarithmic accuracy and match our predictions to next-to-leading-order (NLO) fixed-order results. We perform the calculation in an automated way, for arbitrary electroweak final states and in the presence of kinematic cuts on the leptons produced in the decays of the electroweak bosons. The resummation is based on a factor-ization theorem for the cross sections into hard functions, which encode the virtual corrections to the boson produc-tion process, and beam functions, which describe the low-pT emissions collinear to the beams. The one-loop hard func-tions for arbitrary processes are calculated using the Mad
