Recent analyses by the CDF and D0 Collaborations of jet data produced in p{bar p} collisions at the Fermilab Tevatron Collider are presented. These include new studies of the inclusive jet production cross section, a measurement of the strong coupling constant, the first measurement of subjet multiplicity of quark and gluon jets, examination of ratios of multijet cross sections and their implications for choice of renormalization scale, and a study of charged jet evolution and energy flow in the underlying event. The results are compared to theoretical predictions.

We present results on high[ital p[sub T]] jet physics from the CDF and D[null] experiments at the Fermilab Tevatron Collider. Recent results on the inclusive jet cross-section at[radical][ital s]= 1.8 TeV will be presented and compared with QCD. We will also present results on the dijet angular distribution. Limits on quark compositeness are presented from the CDF dijet angular distribution. Finally we will discuss the results on the inclusive jet cross section at[radical][ital s]= 0.63 TeV and tests of scaling.

An overview of Run I jet physics at the p{bar p} Fermilab Tevatron Collider with a particular emphasis on inclusive jet cross section measurements is given. The impact of these studies on PDFs constrain from global fits is underlined. Preliminary results on inclusive jet and di-jet mass cross section measurements in Run II are then summarized.

Tevatron Run 2 results on the inclusive jet cross section (MidPoint and K{sub T} algorithm) and the b-jet and b{bar b}-jet cross section (MidPoint algorithm) are presented and compared with theory. The CDF b-jet {bar b}-jet {Delta}{phi} distribution is compared with theory and with the D0 jet No. 1-jet No. 2 {Delta}{phi} distribution. The understanding and modeling of the ''underlying event'' in Run 2 at the Tevatron is reviewed and new CDF results are presented.

A brief overview of the latest status of jet physics studies at the Tevatron in proton-antiproton collisions at (square root)s = 1.96 TeV is presented. In particular, measurements of the inclusive jet production cross-section, dijet production and searches for new physics, the ratio of the 3-jet to 2-jet production cross-sections, and the three-jet mass are discussed.

Quantum Chromodynamics (QCD) is the gauge theory that governs the strong interactions between quarks and gluons inside hadrons like, for example, protons and neutrons. At the Tevatron at Fermilab, protons and antiprotons collide at very high energy. In those collisions, collimated jets of hadrons are produced along the direction of struck quarks and gluons in the final state. The measurement of the inclusive jet production cross section for central jets constitutes one of the cornerstones of the jet physics program since it provides a stringent test of pQCD predictions over almost nine orders of magnitude. This Doctoral Thesis presents a measurement of the inclusive jet production cross section using the data collected by the CDF experiment in Run II. The longitudinally invariant Kt algorithm, infrared safe to all orders in pQCD, has been used in order to search for jets in the final state. This measurement is compared to pQCD NLO calculations where non-perturbative effects from the underlying event and the fragmentation of partons into jets of hadrons have been taken into account.

We present the results of searches for non-standard model phenomena in photon and jet final states. These searches use data from integrated luminosities of 0.7-2.7 fb−1 of p{bar p} collisions at (square root)s = 1.96 TeV, collected with the CDF and D0 detectors at the Fermilab Tevatron. No significant excess in data has been observed. We report limits on the parameters of several models, including: large extra dimension, compositeness, leptoquarks, and supersymmetry.

The RunII physics program at the Tevatron started in spring 2001 with protons and antiprotons colliding at an energy of {radical}s = 1.96 TeV. More than 1 fb{sup -1} of data have been collected by both the CDF and D0 experiments. In this contribution, some of the new QCD results are presented.
