Abstract
First measurements of cross sections for isolated prompt photon production in deep inelastic ep scattering have been made using the ZEUS detector at the HERA electron-proton collider using an integrated luminosity of 121 pb -1. A signal for isolated photons in the transverse energy and rapidity ranges 5<ET γ<10GeV and -0.7<ηγ<0.9 was observed for virtualities of the exchanged photon of Q2>35GeV2. Cross sections are presented for inclusive prompt photons and for those accompanied by a single jet in the range ET jet≥6GeV and -1. 5≤ηjet<1.8. Calculations at order α 3αs describe the data reasonably well. © 2004 Elsevier B.V. All rights reserved.
