When the cross section of J/ψproduction is considered as varying with the energy of the nucleon-nucleon interaction,the production of J/ψin pA and A A collisions has been studied by using FRITIOF Model.The calculation shows that the cross section of J/ψproduction“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/ψproduction. 展开更多
