Measurement of the quark to photon fragmentation function through the inclusive production of prompt photons in hadronic Z0 decays
Abstract
The inclusive production of prompt photons with energy above 10 GeV is measured using the OPAL detector in hadronic Z0 decays at LEP. In contrast to previous measurements, the prompt photons were not required to be isolated. The production rate and energy spectrum are found to be in agreement with QCD predictions for the quark-to-photon fragmentation function.
