TL;DR
This paper reports measurements of photon plus jet production at the Tevatron, comparing experimental results with perturbative QCD predictions to test the theory's accuracy in high-energy proton-antiproton collisions.
Contribution
It provides new experimental cross section measurements for photon plus jet, di-photon, and photon plus b jet processes at 1.96 TeV, with detailed comparisons to QCD calculations.
Findings
Measurements agree with QCD predictions within uncertainties
Provides data for testing QCD models at Tevatron energies
Enhances understanding of photon production mechanisms in hadron collisions
Abstract
Photon plus jet production has been studied by the D0 and CDF experiments in Run II of the Fermilab Tevatron Collider at a center of mass energy of sqrt{s}=1.96 TeV. Measurements of the inclusive photon plus jet, di-photon and photon plus b jet cross section are presented. They are based on integrated luminosities between 0.2 fb^-1 and 1.1 fb^-1. The results are compared to perturbative QCD calculations in various approximations.
