Skewed distributions fixed by diagonal partons at small x,\xi and $\gamma^* p \to Vp$ at HERA

TL;DR

This paper demonstrates that skewed parton distributions at small x and  can be fully derived from standard diagonal partons and applies this to analyze diffractive vector meson production at HERA.

Abstract

We show that the skewed parton distributions are completely determined at small x and \xi by the conventional diagonal partons. We study the application to diffractive vector meson production at HERA.
