Kaon and phi production in pion-induced reactions at 1.7 GeV/c — •Joana Wirth1,2, Laura Fabbietti1,2, Steffen Maurus1,2, and Alessandro Scordo3 for the HADES collaboration — 1Physik Department, TUM, Garching, Germany — 2Excellence Cluster "Universe", Garching, Germany — 3LNF, INFN, Frascati, Italy

The production and properties of K+, K and Φ in cold nuclear matter generated in pion-nucleon reactions (π + A, A = C, W) at pπ= 1.7 GeV/c has been investigated with the HADES detector at GSI.
Of particular interest is the K absorption in nuclear matter which should be apparent through strangeness exchange processes (K NYπ), contrary to the K+ with no conventional absorption mechanism due to strangeness conservation. In this context also the Φ absorption (Φ→ K+K, BR∼48.9%) is studied in light and heavy nuclei.
In this talk we are presenting the K absorption on the basis of the K/K+ ratios in both nuclear environments and obtained cross-sections inside the HADES acceptance. In addition the Φ absorption in nuclear medium by comparing the production in carbon and tungsten is shown as well as the K production in terms of the Φ feed-down.
