ISOLATED HARD PHOTON-EMISSION IN HADRONIC Z0 DECAYS

Abstract:
We report on a study of energetic, isolated photons in a sample of ∼ 320 000 Z0 hadronic decays. Energetic isolated photons probe the short-distance structure of QCD. We compare our data with the prediction of several QCD-based calculations. A search for new processes with one or two photons in the hadronic final state is also presented. No evidence for physics beyond the standard model is found. © 1992.
