Inclusive jet cross sections measured at the Fermilab Tevatron proton-antiproton Collider are presented and compared to theoretical predictions. The cross sections are reported as a function of jet transverse energy at beam energies of 630 and 1800 GeV . A recent preliminary result at 1800 GeV by the CDF collaboration confirms an earlier published result which is in good agreement with Quantum Chromodynamics (QCD) below jet transverse energy equal to 250 GeV, but which shows excess jet production above 250 GeV. A final result by the D0 collaboration is in good agreement with QCD at all transverse energy. An uncertainty analysis, including a final D0 systematic error matrix, indicates the two measurements are consistent. Preliminary 630 GeV cross sections from the two experiments are consistent with one another but somewhat lower than QCD predictions. Likewise, preliminary measurements of the ratio of cross sections at 630 and 1800 GeV are experimentally consistent, but approximately 20% below predictions. ** Disclaimer: ** This note has not been internally reviewed by the D0 Collaboration.
