Nuclear structure function at large x and ΛQCD

We explain that due to the presence of the short-range nucleon correlations in nuclei the theoretical pattern of Bjorken scaling violation at x > 0.7 is expected to be simpler here than in lepton-nucleon scattering. Consequently, lepton-nucleus scattering is better suited for the accurate determination of Λ_QCD if nuclear effects are properly accounted for. On the contrary if they are ignored (as it is often done at present) Λ_QCD is considerably underestimated.
