Real Photon to Neutral Pion Ratios and PhotonJet Correlations in Quantum Chromodynamics
Abstract
The real photon to neutral pion ratio and the photonjet (or hadron) correlations in hadronic reactions are studied in the perturbative QCD approach. The γ /π^{0} ratio in pp and bar{p}p collisions are shown to be of order unity. The scaling violation effects and the dependence on the gluon distribution for the photon production cross section are discussed. The two particle inclusive cross sections for the large p_{t} photon and the jet (or hadron) produced on the opposite side of the beams are given in this model. It is shown that experiments of these correlations give informations on the properties of quarks and gluons. A simple test of our model is proposed.
