Title: Probing QCD with photons at the Tevatron

Abstract

Prompt photons with high transverse momenta in pp-bar collisions at {radical}(s) = 1.96TeV at the Tevatron collider have been studied by CDF and DO collaborations. In this paper I present results on production cross-sections for: isolated photons (DO), photons with heavy flavor jets (CDF) and di-photon final states (CDF). The experimental data are compared against predictions of several QCD models.

  • The selected results on QCD jets measured in pp-bar collisions at {radical}(s) = 1.96TeV at the Tevatron Collider at Fermilab are presented in this conference note. The experimental data from CDF and DO detectors are compared against perturbative QCD calculations.
  • A summary of ATLAS measurements that probe 'hard' QCD interactions in the protonproton collisions of the LHC are presented.
  • Photon measurements from the CDF and DO/ collaboration are described. The subjects touched on are loosely organized around the fact that they all have some bearing on the structure functions and pQCD. The methodology of collider measurements is briefly reviewed, and the results for single photons, photons plus jets, photons plus charm and diphotons are discussed. Finally there is a very brief indication of what is expected from the Tevatron based experiments in the future. {copyright} {ital 1997 American Institute of Physics.}
  • Presented are the Run II QCD preliminary results of DO and CDF Collaborations on the measurements of inclusive jet cross sections as well as recently published results on the inclusive and di-photon cross sections.
