摘要：

Measurements of the Drell-Yan process and of charmonium and bottomonium production at CERN and Fermilab show a depletion at high Feynman x in large relative to small nuclear targets. We can attribute this depletion to energy loss of initial and final states, provided that the loss is (dE/dz)Drell-Yan = 4/9 (dE/dz)charm approximately 1.5 GeV/fm at the highest x(F) measured. This small loss is magnified in the differential cross section due to the strong behavior approximately (1 - x)n of the projectile's structure functions at large x.
