Descripción
We present the first measurement of the cross section for direct photon pair production in association with dijet events in proton-antiproton collisions at sqrt(s)=1.96 TeV. We also determine the fraction of events with hard double parton (DP) scattering in a single proton-antiproton collision. Aside from the stringent test of the perturbative QCD predictions, diphoton + dijet production provides an important test of various models of multiple parton interactions.
