We use a sample of diphoton + dijet events, as well as a sample of simultaneous production of two heavy quarkonia (two J/psi or J/psi and Upsilon) collected by the D0 detector at the Fermilab Tevatron collider, to study properties of events with double parton scattering (DPS) in single p¯p collisions at sqrt(s) = 1.96 TeV. We measure the cross sections and extract the effective cross section of double parton interactions in proton-antiproton collisions. Multiple parton interactions are a major background for electroweak precision measurements and new phenomena searches at high energy hadron colliders. These studies provide important information on the parton spatial structure of the nucleon.
