TY - INPR A1 - Soff, Sven T1 - News on strangeness at ultrarelativistic energies - review of microscopic models N2 - Invited talk at the 7th International Conference on Strangeness in Quark Matter, SQM 2003, Atlantic Beach, North Carolina, USA, 12-17 Mar, 2003. 11 pages, 12 figures. Journal-ref: J.Phys. G30 (2004) S139-S150. We review recent developments in the field of microscopic transport model calculations for ultrarelativistic heavy ion collisions. In particular, we focus on the strangeness production, for example, the phi-meson and its role as a messenger of the early phase of the system evolution. Moreover, we discuss the important e ects of the (soft) field properties on the multiparticle system. We outline some current problems of the models as well as possible solutions to them Y1 - 2003 UR - http://publikationen.ub.uni-frankfurt.de/frontdoor/index/index/docId/4839 UR - https://nbn-resolving.org/urn:nbn:de:hebis:30-6614 ER -
