detailed analysis of the polarized (g1) and the unpolarized (F2) deep inelastic scattering structure functions of the proton is presented in the context of a holographic dual description based on type IIB superstring theory. We compare this description with
experimental data and QCD estimates at LO, NLO and NNLO in perturbation. We confront the predictions of a (non-perturbative) holographic dual model and those of perturbative QCD for g1 at the kinematics that will be probed by the forthcoming Electron-Ion Collider.
We find that the extrapolation of g1 to very small values the Bjorken variable computed with a Holographic Pomeron model based on actual data at higher momentum fractions is always positive and differs significantly with standard projections based on perturbative
QCD. </span></p>
