Coherent Power Corrections to Structure Functions

We calculate and resum a perturbative expansion of nuclear enhanced power corrections to the structure functions measured in deeply inelastic scattering of leptons on a nuclear target. Our results for the Bjorken x-, Q2- and A-dependence of nuclear shadowing in F2A(x,Q2) and the nuclear modifications to FLA(x,Q2), obtained in terms of the QCD factorization approach, are consistent with the existing data. We predict the dynamical final state shadowing in v + A reactions for sea and valence quarks in the structure functions F2A(x,Q2) and F3A(x,Q2), respectively. In p + A collisions we calculate the centrality and rapidity dependent nuclear suppression of single and double inclusive hadron production at moderate transverse momenta
