摘要: Using the NMC and E665 nuclear structure function ratios F2A/F2D F2A/F2C from deep inelastic lepton-nucleus collisions, E772 Drell-Yan dilepton cross sections proton-nucleus incorporating baryon number momentum sum rules, we determine parton distributions at an initial scale Q02. With these distributions, study QCD evolution of densities. The emphasis is on small values x, especially dependence shadowing. As main result, show that a consistent picture can be obtained within leading twist DGLAP evolution, in particular, calculated Q2 F2Sn/F2C agrees very well with recent data.
