Abstract：
J/ψ and ψ′production cross sections in fixed-target experiment is calculated, considering the contributions from both color-singlet and color- octet mechanisms. The resultS are applied to the investigations of the J/ψ suppression and the ψ′/ψ ratio problems in p-A collisions. The results agree with the experimental data as the (cc)-nucleon absorption cross sections σ_abs⁸≈10mb for (cc)₈and σ_abs¹≈0mb for (cc) .The model is further used to investigate A-A collisions when comover absorption mechanism is also considered. It is found that the observed experiment data of J/ψ and ψ′/ψ ratio in S-U collisions and Pb-Pb collisions can not be explained consistently within this model. The possibility of QGP formation in S-U and Pb-Pbcollisions is also discussed.
