Geometric scaling in diffractive deep inelastic scattering
C. Marquet, L. Schoeffel
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 Q^2*x^\\lambda, has been argued to be a manifestation of the 
saturation regime of QCD and of the saturation scale Q^2_s(x) x^{-\\lambda}. 
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.
