Geometric scaling in diffractive deep inelastic scattering
C. Marquet, L. Schoeffel
Abstract
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*xλ, has been argued to be a manifestation of the saturation regime of QCD and of the saturation scale Q2s(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.
