Abstract

The isospin and strangeness dimensions of the Equation of State are explored. RIA and the SIS200 accelerator at GSI will allow to explore these regions in compressed baryonic matter. ¹³²Sn+¹³²Sn and ¹⁰⁰Sn+¹⁰⁰Sn collisions as well as the excitation functions of K/π, Λ/π and the centrality dependence of charmonium suppression from the UrQMD and HSD transport models are presented and compared to data. Unambiguous proof for the creation of a 'novel phase of matter' from strangeness and charm yields is not in sight.
