Abstract
In the study of high energy collisions involving hadrons, events in which an isolated high energy photon is observed can provide a direct probe of the underlying parton process, since the emission of these photons is largely unaffected by parton hadronisation. The study of such \prompt" photons gives new perspectives on QCD processes, allowing theoretical models to be tested from new viewpoints. In this talk [1], I present new results from the ZEUS experiment on prompt photons produced in deep inelastic scattering (DIS) at HERA. The process studied is ep→eγX, where e denotes an electron or positron. (Both electrons and positrons will here be referred to as electrons.) The data were taken between 2003 and 2007 with the ZEUS detector and correspond to a total integrated luminosity of 320±8 pb<sup>-1</sup>. The results are compared to two theoretical calculations, from Gehrmann-De Ridder et al. [2] and Martin et al. [3].
