Abstract:By means of the nuclear parton distribution studied only with lepton deep-inelastic scattering experimental data, the J/Ψ “normal nuclear absorption" and energy loss effects are studied in a Glauber formalism at HERA and RHIC energies. Assuming that the absorption cross section σabs increases with the charmonium-nucleon center of mass energy, the results reveal a significant dependence of the σabs on rapidity y at RHIC energies. The initial-state energy loss effect, which is found important only at HERA energi… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
