Abstract

We have measured the dijet angular distribution in

\sqrt{s} = 1.8 TeV p \bar{p}

collisions using the D0 detector. Order

α_{s}^{3}

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.
