Abstract

We have measured the dijet angular distribution in √(s)\phantom\rule0ex0ex=\phantom\rule0ex0ex1.8\phantom\rule0ex0exTeVpp collisions using the D0 detector. Order \ensuremathα_s³ QCD predictions are in good agreement with the data. At 95% confidence limit the data exclude models of quark compositeness in which the contact interaction scale is below 2 TeV.
