GLUON SHADOWING AND CHARMONIUM BOTTONIUM PRODUCTION ON NUCLEAR TARGETS
GUPTA S, Satz H. GLUON SHADOWING AND CHARMONIUM BOTTONIUM PRODUCTION ON NUCLEAR TARGETS. Zeitschrift für Physik C. 1992;55(3):391-396.We examine the suppression of J/psi, psi' and gamma production on nuclear targets, as observed for proton and pion beams of energies from 200 to 800 GeV. We find that this suppression leads to a universal scaling curve, which indicates that it is due to nuclear modifications of the gluon density ("shadowing"). A parametrisation of the nuclear effect on the gluon density is extracted from the data and used to obtain quantitative estimates for corresponding effects in high-energy heavy-ion collisions
