摘要By means of the nuclear parton distribution studied only with lepton deep-inelastic scattering experimental data, the J/psi "normal nuclear absorption" and energy loss effects are studied in a Glauber formalism at HERA and RHIC energies. Assuming that the absorption cross section sigma(abs) increases with the charmonium-nucleon center of mass energy, the results reveal a significant dependence of the sigma(abs) on rapidity y at RHIC energies. The initial-state energy loss effect, which is found important only at HERA energies, is also considered, and its influence should be eliminated when we studied the absorption effect at low collision energies. Finally, we also present the theoretical prediction for LHC.
