Unitarity effects in hard diffraction at HERA

High Energy Physics - Phenomenology 2009-11-10 v1

Abstract

We study how factorization breaking changes when going from diffractive deep inelastic scattering to diffractive photoproduction of dijets. These processes offer a sensitive probe of the interplay of soft and hard mechanisms in QCD. We demonstrate that unitarity effects are already important in the gluon distribution for x ~ 10^{-4}, for quite a wide range of Q^2.
