Recent QCD results from the CDF and D0 experiments at the Fermilab Tevatron collider are reviewed.

The D0 experiment at the Tevatron proton-antiproton collider accumulated a large sample of high energy jet production data during Run I (1992-1996). Presented here are measurements of the inclusive jet cross section at a center-of-mass energy (square root)s = 1800 GeV, and a ratio of central inclusive jet cross sections at two different center-of-mass energies (1800 and 630 GeV). Also included is a measure of the ratio of multijet production cross sections at the higher (square root)s: All measurements are compared to next-to-leading order QCD predictions with recent parton distribution functions (PDFs). Due to decreased statistical and systematic errors in the measurement, comparison with the theory shows that the prediction may benefit from an increased order in the calculation and from inclusion of proton-antiproton jet data in new global PDF fits.

Recent QCD results from the CDF and D0 detectors at the Tevatron proton-antiproton collider are presented. An outlook for future QCD tests at the Tevatron collider is also breifly discussed. 27 refs., 11 figs.

In the last run the Tevatron collider delivered an integrated luminosity of 29.9 pb−1 to CDF and D0. We describe here some preliminary result from analyses of relevant QCD processes in the 1992--1993 data from the two experiments.

Abstract: Recent results of QCD studies from the CDF and D0 experiments at the Tevatron {bar p}p collider at Fermilab are presented. The inclusive jet cross section, the internal structure of jets, di-jet angular distributions, di-jet triple differential cross sections, and properties of multi-jet final states are studied and compared with NLO QCD predictions. The comparisons show good agreement between theoretical predictions and the experimental data in general. Some systematic disagreement between LO predictions and the data are observed in di-jet triple differential cross sections. Results of a rapidity gap study are also presented together with an upper limit on the gap fraction. In addition, the inclusive photon cross section and the di-photon cross sections are presented and compared with NLO QCD predictions.

We present recent QCD results from the D0 experiment at the Fermilab Tevatron Collider in p{bar p} collisions at {radical}s = 1.96TeV. Results are presented for the inclusive jet and dijet cross sections, a measurement of dijet azimuthal decorrelations, studies of elastic scattering, and a search for diffractively produced Z bosons.
