Query: A New Approach of J/psi suppression in pA and AA Collisions   When the cross section of J/psi production is considered varying with the
energy of the nucleon-nucleon interaction the production of J/psi in pA and AA
collisions has been studied using FRITIOF Model. The calculation shows that the
cross section of J/psi production "per nucleon-nucleon collision" decreases
with 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 . We have compared our model
predictions with the experimental data of J/psi production.
