TL;DR

This paper reports a measurement of the dijet invariant mass cross section in proton-antiproton collisions at 1.96 TeV, comparing results with QCD predictions across multiple rapidity regions.

Contribution

The study provides the first detailed measurement of the dijet invariant mass cross section at Tevatron energies across various rapidity ranges.

Findings

Data agrees with next-to-leading order QCD predictions.

Measurement covers six rapidity regions up to 2.4.

Results enhance understanding of jet production at Tevatron energies.

Abstract

The inclusive dijet production double differential cross section as a function of the dijet invariant mass and of the largest absolute rapidity of the two jets with the largest transverse momentum in an event is measured in proton anti-proton collisions at sqrt{s} = 1.96 TeV using 0.7 fb^{-1} integrated luminosity collected with the D0 detector at the Fermilab Tevatron Collider. The measurement is performed in six rapidity regions up to a maximum rapidity of 2.4. Next-to-leading order perturbative QCD predictions are found to be in agreement with the data.
