A New Approach of J/psi suppression in pA and AA Collisions
Tai An, Chao Wei Qin, Yao Xiao Xia
Abstract
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.
