【 摘 要 】

At the Fermilab Tevatron energies, (3-1800 GeV and 3-630 GeV), jet production is the dominant process. During the period 1992-1996, the theta and CDF experiments accumulated almost 100 pb-1 of data and performed the most accurate jet production measurements up to this date. These measurements and the NLO-QCD theoretical predictions calculated during the last decade, have improved our understanding of QCD, our knowledge of the proton structure, and pushed the limit to the scale associated with quark compositeness to 2.4-2.7 TeV. In this paper, we present the most recent published and preliminary measurements on jet production and fragmentation by the Dtheta and CDF collaborations.
