Résumé

The geometric scaling property observed in the HERA data at small x, that the deep inelastic scattering (DIS) total cross-section is a function of only the variable Q² x^λ, has been argued to be a manifestation of the saturation regime of QCD and of the saturation scale Q_s² (x) ∼ x^{- λ}. We show that this implies a similar scaling in the context of diffractive DIS and we observe, for several diffractive observables, that the experimental data from HERA confirm the expectations of this scaling.
