Contribution

It provides the most recent jet production and fragmentation measurements from D0 and CDF, enhancing the precision of QCD tests and proton structure knowledge.

Findings

Jet production measurements agree with NLO-QCD predictions

Limits on quark compositeness set at 2.4-2.7 TeV

Improved understanding of QCD at Tevatron energies

Abstract

At the Fermilab Tevatron energies, ($\sqrt{s}$=1800 GeV and $\sqrt{s}$=630 GeV), jet production is the dominant process. During the period 1992-1996, the D0 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 D0 and CDF collaborations.
