Title: Semi-exclusive deeply virtual Compton scattering

Abstract

We consider Semi-Exclusive Deeply Virtual Compton Scattering, {gamma}*p{yields}{gamma}Y (SECS), where Y is an inclusive state of intermediate mass, {lambda}{sub QCD}<<m{sub Y}<<Q. When the photon is produced with a large transverse momentum k{sub perpendicular}{approx}m{sub Y} the subprocess is hard and the struck quark fragments independently of the target spectators. Using completeness this allows us to express the SECS cross section in terms of ordinary parton distributions. Apart from direct comparisons with data (yet to come) new information on Bloom-Gilman duality may be obtained through comparisons of resonance production via DVCS ({gamma}*p{yields}{gamma}N*) with the SECS scaling distribution in m{sub Y}.
