Query: Inclusive Jet Cross Sections in $\bar{p}p$ Collisions at $\sqrt{s}$= 630
  and 1800 GeV   We have made a precise measurement of the inclusive jet cross section at
$\sqrt{s}$=1800 GeV. The result is based on an integrated luminosity of 92
pb^{-1} collected at the Fermilab Tevatron $\bar{p}p$ Collider with the D\O
detector. The measurement is reported as a function of jet transverse energy
(60 GeV <= E_{T} < 550 GeV), and in the pseudorapidity intervals |\eta| <= 0.5
and 0.1 <= |\eta| <= 0.7. A preliminary measurement of the pseudorapidity
dependence of inclusive jet production (|\eta| <= 1.5) is also discussed. The
results are in good agreement with predictions from next-to-leading order (NLO)
quantum chromodynamics (QCD). D\O has also determined the ratio of jet cross
sections at $\sqrt{s}$=630 GeV and $\sqrt{s}$=1800 GeV (|\eta| <= 0.5). This
preliminary measurement differs from NLO QCD predictions.
