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.

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.

Results on recent QCD measurements performed at the Tevatron p{bar p} Collider at (square root)s = 1.96 TeV are here reported. The inclusive jet and dijet mass cross sections are compared to NLO pQCD calculations and to Run I results. The production rates and kinematic properties of W + jets production processes are compared to ''enhanced'' LO theoretical predictions. Non-perturbative ''soft'' interactions leading to the underlying event are studied and compared to QCD Monte Carlo phenomenological models.
