Résumé : Measurements from the H1 and ZEUS collaborations of the diffractive deep-inelastic scattering process, ep → eXY, where Y is a proton or a low mass proton excitation, are presented for photon virtualities in the range 2.2 < Q 2 < 1600 GeV 2 and squared four-momentum transfer at the proton vertex satisfying t < 1 GeV 2. Diffractive parton distribution functions and their uncertainties are determined from a next-to-leading order DGLAP QCD analysis. Combining measurements of the inclusive diffractive deep-inelastic scattering process with an analysis of diffractive dijet production allows a very sensitive determination of both quark and gluon distributions.
