Investigations of J/Ψ Anomalous Suppressions in Pb-Pb Collisions at 158 AGeV/c

摘要: 在核吸收与随动者吸收理论的基础上,给出了在有QGP相变情况下高能重离子碰撞中的J/Ψ微分产生截面,并用其讨论了CERN的NA50合作组给出的入射动量为158 AGeV/c的Pb-Pb碰撞中的J/Ψ反常抑制现象。理论较好地解释了实验结果。

Abstract: On the basis of nuclear and comover absorption theories,we have derived out the differential cross section of J/Ψ production in high-energy heavy-ion collisions under the situation that QGP phase transition occurs,and analyzed the experimental data of NA50 Collaboration at CERN in Pb-Pb collisions at 158 AGeV/c.Our theory favors the data well.
