Diffractive production of charm and jets at HERA

Abstract

Measurements are presented of dijet cross sections in diffractive photoproduction and of D*(+/-) production in diffractive deep inelastic scattering at HERA. A combined QCD analysis of the diffractive dijet cross sections and diffractive structure function results leads to a picture in which the pomeron has a substantial gluon component with a hard momentum spectrum
