Résumé

Results are presented from analyses of jet data produced in pp collisions at > /s = 630 and 1800 GeV collected with the D0 detector during the 1994-1995 Fermilab Tevatron Collider run. We discuss the details of detector calibration, and jet selection criteria in measurements of various jet production cross sections at s = 630 and 1800 GeV. The inclusive jet cross sections, the dijet mass spectrum, the dijet angular distributions, and the ratio of inclusive jet cross sections at \fs= 630 and 1800 GeV are compared to next-to-leadingorder QCD predictions. The order o^ calculations are in good agreement with the data. We also use the data at V?= 1800 GeV to rule out models of quark compositeness with a contact interaction scale less than 2.2 TeV at the 95% confidence level.
