Description
The data on hadron production in nuclei exhibit two striking regularities which are not readily explained by conventional hadron dynamics: (1) The mass-number dependence Aα(xF) of inclusive production cross sections has a universal power α(xF), which is independent of the produced hadron. (2) The A dependence of J/ψ production in nuclei has two distinct components: an A1 contribution at low xF and an anomalous A2/3 contribution which dominates at large xF. We show that both phenomena can be understood in QCD as a consequence of the nucleus filtering out small, color-singlet Fock-state components of the incident-hadron wave function
