摘要：

We perform a chi(2) analysis of nuclear parton distribution functions (NPDFs) using neutral current charged-lepton (l(+/-)A) deeply inelastic scattering (DIS), and Drell-Yan data for several nuclear targets. The nuclear A dependence of the NPDFs is extracted in a next-to-leading order fit. We compare the nuclear corrections factors (F-2(Fe)/F-2(D)) for this charged-lepton data with other results from the literature. In particular, we compare and contrast fits based upon the charged-lepton DIS data with those using neutrino-nucleon DIS data.
