Measurement of long-lived strange resonances in FOPI^* — •Markus Merschmeyer — Physikalisches Institut der Universität Heidelberg

K⁰ and Λ have been measured in the reactions Ni+Ni at 1.93 AGeV and Ru+Ru at 1.69 AGeV. Spectra and rapidity distributions are discussed and point, as is the case for charged kaons, in the theoretical description to the necessity for introducing in-medium potentials. Further information on this topic can be gained from the investigation of subthreshold production of double strange baryons at SIS energies. The capability of the FOPI detector for measuring Ξ⁻ and theoretical predictions from thermal model calculations are presented.
