标题： Interplay of Soft and Hard Interactions in Nuclear Shadowing at High $Q^2$ and Low x

摘要： 核阴影修正主要由软相互作用主导，并且作为 $1/x$ 的函数增长得比单散射项慢，而单散射项则有硬相互作用的重要贡献。因此，我们预测，在非常低的 $x$ 下核阴影消失，前提是 $Q^2$ 高且固定。同时，在中等和较低的 $Q^2$ 下，随着 $1/x$ 的增加，核阴影会增长，这与软强子相互作用的情况一样众所周知。 显示英文摘要

摘要： 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 $Q^2$ is high and fixed. At the same time, at medium and low $Q^2$, nuclear shadowing grows with $1/x$ as is well known for soft hadronic interactions.
