Abstract
Results are presented from analyses of jet data produced in $p\overline{p}$ collisions at $\sqrt{s}=630$ and 1800 GeV collected with the D\O{} 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 $\sqrt{s}=630$ 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 $\sqrt{s}=630$ and 1800 GeV are compared to next-to-leading-order QCD predictions. The order ${\ensuremath{\alpha}}_{\mathrm{s}}^{3}$ calculations are in good agreement with the data. We also use the data at $\sqrt{s}=1800$ GeV to rule out models of quark compositeness with a contact interaction scale less than $2.2$ TeV at the $95%$ confidence level.
