摘要：

We present a description of the A dependence of heavy-quark and Drell-Yan pair production in hadron-nucleus collisions, based on the Reggeon approach to strong interactions at high energies and the parton model. The same method has been successfully applied to the production of light-quark states. The existence of a new energy scale, which depends on the mass and x(F) of the heavy system, is emphasized. A phenomenological model, which includes both the shadowing corrections to the nucleon structure function and the rescattering of the heavy-quark states, is proposed. The model quantitatively describes the available experimental data on J/psi and heavy lepton-pair production in h A collisions as well as the European Muon Collaboration effect at low x.
