Abstract:
The cross-section for deeply virtual Compton scattering in the reaction ep --> egammap has been measured with the ZEUS detector at HERA using integrated luminosities of 95.0 pb(-1) of e(+) p and 16.7 pb(-1) of e(-) p collisions. Differential cross-sections are presented as a function of the exchanged-photon virtuality, Q(2), and the centre-of-mass energy, W, of the gamma*p system in the region 5 < Q(2) < 100 GeV(2) and 40 < W < 140 GeV. The measured cross-sections rise steeply with increasing W. The measurements are compared to QCD-based calculations. (C) 2003 Elsevier B.V. All rights reserved.
