Abstract
We present an event generator for the process pp→ℓνℓγ at next-to-next-to-leading order (NNLO) in QCD and matched to the PYTHIA8 parton shower. The calculation makes use of the GENEVA framework, which combines a resummed calculation obtained via Soft-Collinear Effective Theory (SCET) with the fixed-order result. We validate the NNLO accuracy of our results by comparing predictions for inclusive quantities with an independent fixed-order calculation, and then present the resummed partonic 0-jettiness spectrum at next-to-next-to-leading logarithmic (NNLL′) accuracy. Finally, we compare our predictions against data collected by the ATLAS experiment at the Large Hadron Collider during its 7 TeV run, finding good agreement.
