Production of Isolated Photons in Deep Inelastic Scattering
  We present here the predictions obtained from a calculation of the inclusive isolated photon production cross section in deep inelastic scattering. The results are compared with the cross section measurement of the ZEUS collaboration and found in good agreement with all aspects of it. Furthermore, a way of measuring the quark-to-photon fragmention function in DIS is also briefly outlined.
