Ratios of strange antibaryons to baryons in relativistic nucleus-nucleus collisions
- CCAST (World Laboratory), P.O. Box 8730 Beijing (China)
Ratios of strange antibaryons to baryons in the reaction S + Pb at 200{ital A} GeV beam energy have been computed using a new version of the Fritiof event generator, Luciae, with collective string interaction and rescattering. Theoretical ratios of {bar {Lambda}}/{Lambda}, {Xi}{sup {minus}}/{Lambda}, {bar {Xi}}{sup {minus}}/{bar {Lambda}}, and {bar {Xi}}{sup {minus}}/{Xi}{sup {minus}} are comparable with experimental data within the range of the deviation among the data of different collaborations. It seems to indicate that the ratios of production of strange antibaryons to baryons might be explained within a hadronic scenario.
