Study of double parton interactions in diphoton +dijet events in p p ¯ collisions at √{s }=1.96 TeV
Abstract
We use a sample of diphoton+dijet events to measure the effective cross section of double parton interactions, which characterizes the area containing the interacting partons in proton-antiproton collisions, and find it to be σeff=19.3 ±1.4 (stat)±7.8 (syst) mb . The sample was collected by the D0 detector at the Fermilab Tevatron collider in p p ¯ collisions at √{s }=1.96 TeV and corresponds to an integrated luminosity of 8.7 fb-1 .
