| 英文摘要 | J/psi and psi' 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/psi suppression and the psi'/psi ratio problems in p-A collisions. The results agree with the experimental data as the (c (c) over bar)-nucleon absorption cross sections sigma(abs)(8) approximate to 10mb for (c (c) over bar)(8) and sigma(abs)(1) approximate to 0mb for (c (c) over bar)(1). The model is further used to investigate A-h collisions when comover absorption mechanism is also considered. It is found that the observed experiment data of J/psi and psi'/psi 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-Pb collisions is also discussed. |
