Description

Two measurements of the properties of double parton scattering in $p\bar{p}$ collisions at $\sqrt{s} = 1.96$ TeV are presented through measurement of the cross sections of simultaneous production of two heavy quarkonia (two J/psi or J/psi and Upsilon) or the production of diphoton + dijet events. 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.
