摘要：

We explore the combined role of inelastic final-state scattering with nucleons and comoving secondary particles in the suppression of J ψ production for hadron-nucleus and nucleus-nucleus collisions, as functions of target mass, beam energy, and transverse energy. Our interpretation of recent data suggests that nuclear scattering dominates the suppression for π + A collisions at 125 GeV while a comparable contribution from scattering in a dense comover gas emerges for O + U and S + U at 200 AGeV. © 1990.
