TL;DR

This paper presents measurements of the inclusive jet cross section in proton-antiproton collisions at 1.96 TeV using the k_T algorithm, comparing results with next-to-leading order QCD predictions across various rapidity regions.

Contribution

First measurement of the inclusive jet cross section using the k_T algorithm at Tevatron energies with detailed rapidity and transverse momentum coverage.

Findings

Measured cross sections agree with NLO QCD predictions.

Performed in five different jet rapidity regions.

Covered transverse momentum range from 54 to 700 GeV/c.

Abstract

We report on measurements of the inclusive jet production cross section as a function of the jet transverse momentum in pp-bar collisions at sqrt{s} = 1.96 TeV}, using the k_T algorithm and a data sample corresponding to 1.0 fb^-1 collected with the Collider Detector at Fermilab in Run II. The measurements are carried out in five different jet rapidity regions with |yjet| < 2.1 and transverse momentum in the range 54 < \ptjet < 700 GeV/c. Next-to-leading order perturbative QCD predictions are in good agreement with the measured cross sections.
