Description

We use a sample of diphoton + dijet events collected using the D0 detector at the Fermilab Tevatron Collider to measure the effective cross section of double parton interactions in proton-antiproton collisions at √s=1.96 TeV. We also study the simultaneous production of two heavy quarkonia (two J/ψ or J/ψ and Υ) to extract the effective cross section of double parton interactions. We report the first evidence for the simultaneous production of J/ψ and Υ.
