A preliminary measurement of the inclusive jet cross section at (square root){ital s} = 630 GeV is presented. The data are compared with NLO QCD predictions. The ratio of scaled inclusive jet cross section a (square root){ital s} = 1800 GeV and (square root){ital s} = 630 GeV is presented and compared with previous CDF results and QCD predictions.

Inclusive jet cross-sections have been measured in {bar p}p collisions at (square root)s = 546 and 1,800 GeV, using the CDF detector at the Fermilab Tevatron. The ratio of low E{sub t} (25--75 GeV) jet cross sections vs. E{sub t} has been formed, and the authors have used this as a tool to investigate some implications of the published 1989 CDF ''jet scaling'' results. In particular, results at 1,800 GeV have given no indication of any unsuspected errors in CDF's low E{sub t} jet measurements.

Measurements of the inclusive jet cross section with the anti-kt clustering algorithm are presented for two radius parameters, R=0.5 and 0.7. They are based on data from LHC proton-proton collisions at $\sqrt{s}$ = 7 TeV corresponding to an integrated luminosity of 5.0 inverse femtobarns collected with the CMS detector in 2011. The ratio of these two measurements is obtained as a function of the rapidity and transverse momentum of the jets. Significant discrepancies are found comparing the data to leading-order simulations and to fixed-order calculations at next-to-leading order, corrected for nonperturbative effects, whereas simulations with next-to-leading-order matrix elements matched to parton showers describe the data best.

The QCD corrections to W production associated with a jet are studied using the ratio of W + 1 Jet to W + 0 Jets cross sections for a jet with a transverse energy of 25 GeV. The measured ratio of $0.096\pm0.005\sp{stat}\pm0.008\sp{syst}$ is significantly higher than the theoretical predictions of Giele et al. of 0.053. This discrepancy is at least partly due to the relatively unconstrained gluon distribution of the proton.
