Coherent power corrections to structure functions
Abstract
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-, Q**2- and A-dependence of nuclear shadowing in F2(x,Q**2;A) and the nuclear modifications to FL(x,Q**2;A), obtained in terms of the QCD factorization approach, are consistent with the existing data. We predict the dynamical shadowing from final state interactions in neutrino-nucleus reactions for sea and valence quarks in the structure functions F2(x,Q**2;A) and xF3(x,Q**2;A), 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.
