TL;DR

This paper reports a measurement of the inclusive jet cross section in proton-antiproton collisions at 1.8 TeV using the kT algorithm, showing general agreement with QCD predictions except at low transverse momentum.

Contribution

First measurement of the inclusive jet cross section using the kT algorithm at the Tevatron with detailed comparison to QCD.

Findings

Cross section agrees with QCD at high pT

Marginal agreement at low pT

Provides data for testing QCD models

Abstract

The central inclusive jet cross section has been measured using a successive-combination algorithm for reconstruction of jets. The measurement uses 87.3 pb^{-1} of data collected with the D0 detector at the Fermilab Tevatron ppbar Collider during 1994-1995. The cross section, reported as a function of transverse momentum (pT>60 GeV) in the central region of pseudorapidity (|\eta|<0.5), exhibits reasonable agreement with next-to-leading order QCD predictions, except at low pT where the agreement is marginal.
