Measurement of the Inclusive Jet Cross Section in ppbar Interactions at sqrt{s}=1.96 TeV Using a Cone-based Jet Algorithm

CDF Collaboration

Abstract

We present a measurement of the inclusive jet cross section in ppbar interactions at sqrt{s}=1.96 TeV using 385 pb^{-1} of data collected with the CDF II detector at the Fermilab Tevatron. The results are obtained using an improved cone-based jet algorithm (Midpoint). The data cover the jet transverse momentum range from 61 to 620 GeV/c, extending the reach by almost 150 GeV/c compared with previous measurements at the Tevatron. The results are in good agreement with next-to-leading order perturbative QCD predictions using the CTEQ6.1M parton distribution functions.

Figures (2)

  • Figure 1: The measured inclusive jet differential cross section corrected to the parton level compared to the NLO pQCD prediction of the EKS calculation using CTEQ6.1M.
  • Figure 2: The ratio of the data corrected to the parton level over the NLO pQCD prediction of the EKS calculation using CTEQ6.1M. Also shown are the experimental systematic errors and the theoretical errors from the PDF uncertainty. The ratio of MRST2004/CTEQ6.1M is shown as the dashed line. An additional 6% uncertainty on the determination of the luminosity is not shown.
