Production of Jets at the Tevatron

TL;DR

This paper reports measurements of jet production at the Tevatron, comparing experimental data with QCD predictions, and sets limits on quark compositeness based on dijet angular distributions.

Contribution

It provides detailed measurements of jet cross sections and angular distributions, and constrains new physics beyond the Standard Model.

Findings

Good agreement with QCD below 250 GeV

Excess observed at higher ET in CDF data

Quark compositeness excluded below 2.1 TeV

Abstract

Measurements of the inclusive jet cross section and the dijet angular distribution using data from the Tevatron are presented. Comparisons to NLO QCD show good agreement below 250 GeV, but CDF data show an excess at higher ET; qualitative agreement is seen between the CDF and DO cross sections. Analysis of the dijet angular distributions exclude quark compositeness below 2.1 TeV.
