摘要：

We study how much gluon shadowing can be perturbatively generated through the modified QCD evolution in heavy nuclei. We model in simultaneously fusions from independent constituents and from the same constituent, both in a proton and in a large loosely bound nucleus of A approximately 200. In addition to the actual distributions at small x, we study the ratios of the distributions at an initial scale Q0 = 2 GeV, and show that a strong nuclear shadowing can follow from the modified QCD evolution.
