Résumé : I present measurements of dijet and open charm cross-sections in diffractive DIS and photoproduction taken with the H1 and ZEUS detectors at the HERA accelerator. Diffractive events were identified by a rapidity gap selection. The resulting differential cross sections are compared to QCD calculations in NLO, based on parton densities extracted from inclusive diffraction. Additionally a fit of diffractive parton densities to the combined data sets of the inclusive F2 D measurement and the dijet data was performed. This leads to reduced uncertainties for the gluon density.
