摘要

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 xalign=center border=0 SRC=/images/glyphs/BKF.GIF>10⁻⁴, for quite a wide range of Q².
