Abstract
The centrality dependence of Xi^- and Lambda production in Au+Au interactions at E_lab=6 AGeV is studied within a microscopic transport approach. In line with recent data, a slight enhancement of the Xi^-/(Lambda+Sigma^0) ratio toward central collisions is found. It is demonstrated that the observed production of multiple strange baryons can be traced back to multi-step meson-baryon interactions in the late stages of the collisions. Therefore, the present analysis supports an interpretation of the observed Xi abundance in terms of hadronic re-scattering.
