Ratios of strange antibaryons to baryons in relativistic
nucleus-nucleus collisions
Sa Ben-Hao,Tai An and Lu Zhong-Dao
Ratios of strange antibaryons to baryons in the reaction S + Pb at
200 AGeV beam energy have been computed using a new version of the
Fritiof event generator, Luciae,with collective string interaction
and rescattering. Theoretical ratios of $\overline{\Lambda}$/$
\Lambda$,$\Xi^-$/$\Lambda$,$\overline{\Xi^-}$/$\overline{\Lambda}$
and $\overline{\Xi^-}$/$\Xi^-$ 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.
