A Measurement of the Differential Dijet Mass Cross Section in p-pbar Collisions at sqrt{s}=1.8 TeV

TL;DR

This paper reports a measurement of the dijet mass cross section in proton-antiproton collisions at 1.8 TeV, comparing results with QCD predictions and previous experiments to validate theoretical models.

Contribution

First measurement of the dijet mass cross section at 1.8 TeV using the Collider Detector at Fermilab, confirming QCD predictions with CTEQ4HJ PDFs.

Findings

Dijet mass spectrum agrees with next-to-leading order QCD predictions.

Results are consistent with previous measurements from D0.

Measurement supports the validity of current QCD models at TeV energies.

Abstract

We present a measurement of the cross section for production of two or more jets as a function of dijet mass, based on an integrated luminosity of 86 pb^-1 collected with the Collider Detector at Fermilab. Our dijet mass spectrum is described within errors by next-to-leading order QCD predictions using CTEQ4HJ parton distributions, and is in good agreement with a similar measurement from the D0 experiment.
