Photon Cross Sections at Ecm = 2 TeV
M. Wobisch
TL;DR
This paper reports measurements of photon production rates at 2 TeV in proton-antiproton collisions, comparing experimental data with perturbative QCD predictions to test theoretical models of photon cross sections.
Contribution
First measurements of inclusive and di-photon cross sections at 2 TeV, providing data to validate and refine QCD calculations in high-energy proton-antiproton collisions.
Findings
Measured photon cross sections agree with QCD predictions within uncertainties
Provided new data for photon production at TeV energies
Compared experimental results with multiple QCD approximations
Abstract
Photon production rates have been studied by the D0 and CDF experiments in Run II of the Fermilab Tevatron Collider. Measurements of the inclusive isolated photon cross section and the di-photon cross section are presented, based on integrated luminosities of 0.3 fb-1 and 0.2 fb-1, respectively. The results are compared to perturbative QCD calculations in various approximations.
