Abstract

A measurement of the cross-sections for single and double prompt photon production in ppBAR interactions at square-root s = 630 GeV is presented. The data sample corresponds to an integrated luminosity of 13.2 pb-1. The results are in good agreement with,the predictions of perturbative QCD. The signal from double prompt photon production has a statistical significance of 4.3 standard deviations.
