Zγ production at hadron colliders in NNLO QCD


Grazzini, Massimiliano; Kallweit, Stefan; Rathlev, Dirk; Torre, Alessandro (2014). Zγ production at hadron colliders in NNLO QCD. Physics Letters B, 731:204-207.

Abstract

We consider the production of Zγ pairs at hadron colliders. We report on the first complete and fully differential computation of radiative corrections at next-to-next-to-leading order in QCD perturbation theory. We present selected numerical results for pp collisions at 7 TeV and compare them to available LHC data. We find that the impact of the NNLO QCD corrections on the fiducial cross section ranges between 4 and 15%, depending on the applied cuts.
