Next-to-leading order γ γ + 2 − jet production at the LHC

We present next-to-leading-order QCD predictions for cross sections and for a comprehensive set of distributions in gamma gamma + 2-jet production at the Large Hadron Collider. We consider the contributions from loop amplitudes for two photons and four gluons, but we neglect top quarks. We use BLACK...

Description
Summary:We present next-to-leading-order QCD predictions for cross sections and for a comprehensive set of distributions in gamma gamma + 2-jet production at the Large Hadron Collider. We consider the contributions from loop amplitudes for two photons and four gluons, but we neglect top quarks. We use BLACKHAT together with SHERPA to carry out the computation. We use a Frixione cone isolation for the photons. We study standard sets of cuts on the jets and the photons and also sets of cuts appropriate for studying backgrounds to Higgs-boson production via vector-boson fusion.
