| 英文摘要 | In this paper, the J/psi nuclear absorption effect is studied at RHIC and LHC energies with the EKS98 shadowing parameterizations. By assuming that the J/psi absorption cross section, sigma(abs), increases with the charmonium-nucleon (J/psi-N) center of mass energy, root(s)J/psi N, it is found that sigma(abs) should depend on x(F) (or y) at a certain center of mass energy per nucleon pair, root s especially at LHC energies. The theoretical results with the x(F) (or y)-dependence of the absorption effect are in good agreement with the experiment data from PHENIX in d-Au collisions and the predicted results will be examined by the forthcoming experimental data from LHC in d-Pb collisions. Finally, we also present baseline calculations of cold nuclear matter effects on J/psi production in nucleus-nucleus (A-A) collisions and find that the x(F) (or y)-dependence of absorption effect is very small at both RHIC and LHC energies in A-A collisions. |
