| 英文摘要 | We have used the event generator LUCIAE to analyze the data of singly strange particle production in pp, pA, and AA reactions at 200A GeV and compared them with the corresponding experimental data and theoretical results of HIJING, VENUS, and RQMD. The results indicate that for reproducing the NA35 data of AA reactions it requires a somewhat larger s quark suppression factor (s=0.3) and shorter Formation time (tau=1 fm/c) of produced particles than for reproducing the experimental data of pp and pA (s=0.2 and tau=1.5 fm/c). This might be understood intuitively from the relationship between the effective string tension and the violence of collision. However, the NA36 data of the negative multiplicity dependence of Lambda in S + Pb reaction at 200 A GeV could not be well reproduced by LUCIAE, VENUS, or RQMD, and the NA36 data prefers model parameters of s=0.2 and tau=1.5 fm/c especially, this seems hard to understand and needs further studies. From comparing the NA35 data of the rapidity distribution of Lambda in S + Ag reactions to the corresponding results of LUCIAE one knows that the effect of varying the s quark suppression factor from 0.2 to 0.3 is smaller than the effect of rescattering with respect to strangeness production. |
