✦ Synopsis

We have made a precise measurement of the inclusive jet cross section at x/~=1800 GeV. The result is based on an integrated luminosity of 92 pb -1 collected at the Fermilab Tevatron ~p Collider with the DO detector. The measurement is reported as a function of jet transverse energy (60 GeV -< ET -< 500 GeV ), and in the pseudorapidity intervals Ir/[ < 0.5 and 0.1< I~?1 <0.7. A preliminary measurement of the pseudorapidity dependence of inclusive jet production (mql _< 1.5 ) is also discussed. The results are in good agreement with predictions from next-to-leading order (NLO) quantum chromodynamics (QCD). DO has also determined the ratio of jet cross sections at ff'~----630 GeV and vf~=1800 GeV (Ir/I -< 0.5). This preliminary measurement differs from NLO QCD predictions.
