| 英文摘要 | The mechanisms of the energy degradation of leading particle, of the effective dissociation of C (C) over bar pair (the precursor of physical J/psi) in the colour electric field of strings, and of the hadronic absorption (both baryon and meson) are introduced into the proposed hadron and string cascade model, JPCIAE. That has been used to calculate the J/psi suppression factors in pA, AB (with light projectile), and Pb + Pb collisions at 200 A GeV/c energy. The theoretical results reproduce simultaneously both the corresponding NA38 and NA50 data fairly well, which arises the question of whether there art J/psi anomalous suppressions in 158 A GeV/c Pb + Pb collisions. |
