Interplay of Soft and Hard Interactions in Nuclear Shadowing at High Q2 and Low x
B. Z. Kopeliovich, B. Povh
Abstract
Nuclear shadowing corrections are dominated by soft interaction and grow as function of 1/x more slowly than the single scattering term, which has an essential contribution from hard interaction. Therefore, we predict vanishing nuclear shadowing at very low x provided that Q2 is high and fixed. At the same time, at medium and low Q2, nuclear shadowing grows with 1/x as is well known for soft hadronic interactions.
