Recent results from FOPI From the dynamics of heavy ion collisions to the (Anti)Kaon-nucleon potential

摘要

Strange particles allow to probe the properties of hot and dense baryonic matter. At incident energies close to the production threshold medium effects on the strange hadrons are magnified. New data obtained with the recently completed FOPI upgrade are presented for the system Ni+Ni at 1.91 AGeV and discussed in comparison to earlier findings.
