Contribution

It introduces an improved cone-based jet algorithm (Midpoint) and extends the jet transverse momentum range for cross section measurements at the Tevatron.

Findings

Results agree with next-to-leading order perturbative QCD predictions.

Extended the jet transverse momentum range by nearly 150 GeV/c.

Provided the most precise measurements at this energy to date.

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.
