AbstractDijet angular distributions provide a excellent look at the interactions between partons. The measurements performed by the DO detector are the most precise accomplished to date at pp colliders and cover a larger angular range than previously possible. Both leading order and next-to-leading order QCD calculations show agreement with the data over a large range in dijet invariant mass. This comparison is limited mainly by the large size of the theoretical uncertainties which are larger than the experimental uncertainties for some mass ranges. Additionally, a limit on quark compositeness of Λ(C) > 1.1 TeV has been obtained.
