Comparison at NLO between Predictions from QCD Fits to F2D and Diffractive Final State Observables at HERA --------------------------------------------------------------------------- Diffractive parton distributions, obtained from a next-to-leading order QCD analysis of recent H1 inclusive diffractive deep-inelastic scattering data, are convoluted with QCD hard scattering matrix elements to predict cross sections at next-to-leading order for the diffractive production of jets and charm quarks off virtual photons. The predictions are compared with H1 measurements of dijet and D^* meson production cross sections in diffractive DIS. Within the experimental and theoretical uncertainties, the results are consistent with QCD factorisation in diffractive DIS at NLO.
