DVCS at HERA
L. Frankfurt, A. Freund, M. Strikman
We demonstrate that perturbative QCD allows one to calculate the absolute cross section of diffractive exclusive production of photons at large at HERA, while the aligned jet…
Deeply Virtual Compton Scattering at HERA - A Probe of Asymptotia
L. Frankfurt, A. Freund, M. Strikman
We demonstrate that the measurement of an azimuthal angle asymmetry in deeply virtual Compton scattering (DVCS) at HERA energies, is experimentally feasible and allows one to deter…
Study of Nondiagonal Parton Distribution Models
Andreas Freund, Vadim Guzey
In this paper we examine predictions from different models of nondiagonal parton distributions. This will be achieved by examining whether certain predictions of relationships betw…
Proof of Factorization for Deeply Virtual Compton Scattering in QCD
John C. Collins, Andreas Freund
We show that factorization holds for the deeply virtual Compton scattering amplitude in QCD, up to power suppressed terms, to all orders in perturbation theory. Furthermore, we sho…
