Nuclear Deep Inelastic Scattering around x=0.3
Abstract
Deep-inelastic scattering (DIS) data on nuclei, from deuterium to lead, indicate that nuclear effects on the partonic structure of bound nucleons are remarkably small around x=0.3, where valence-quark distributions peak. We present the results of a global analysis of DIS data on the cross-section ratios σA/σ2H in the range 0.25 ≤ x ≤ 0.35, revealing a remarkable cancellation of nuclear effects across the entire range of nuclear targets. We also discuss the interpretation of such an observation within a microscopic model of nuclear modifications of the structure functions.
