Abstract When the cross section of J/ψ production is considered as varying with the energy of the nucleon-nucleon interaction, the production of J/ψ in pA and A A collisions has been studied by using FRITIOF Model. The calculation shows that the cross section of J/ψ production “per nucleon-nucleon collision” decreases with the increasing mass number and centrality as a consequence of continuous energy loss of the projectile nucleons to the target nucleons in their successive binary nucleon-nucleon collisions. The model predictions have been compared with the experimental data of J/ψ production.
