Abstract

We have calculated within the QCD frame-work the inclusive one and two particle production cross sections triggering on a photon or a π0 for incident protons and antiprotons. The results are compared and shown to be in good agreement with all pertinent experimental data, provided a hard gluon structure function is used. The γ/π0 ratio as well as the ratio of bremsstrahlung to directly produced γ's are examined as a function of rapidity andpT. Results are presented for c.m. energies\(\sqrt s = 62\) and 800 GeV
