Charged kaons in FOPI spectrometer — •Zbigniew Tyminski — Gesellschaft für Schwerionenforschung, Darmstadt, Germany — Warsaw University, Warsaw, Poland

Most models predict the change of the properties of kaons when they are immersed in the nuclear medium, e.g. their mass depends on the density of the baryonic nuclear medium. SIS energy regime is well suited for the investigating of modification of strangeness production and propagation processes due to the presence of the baryonic medium. The FOPI collaboration has successfully measured kaons and anti-kaons at various incident energies and in different collision systems. We present an update of the systematics of charged kaons production as a function of system size [1], K⁺/K⁻ ratio dependence on rapidity and transverse momentum [2] and differential flow of K⁺ [3] as well as an outlook for the possibilities from planed experiments.
