Search for kaonic clusters in nuclear collisions at SIS18 — •Laura Fabbietti for the FOPI collaboration — Technische Universität München

Recently a new method to study in-medium hadron-mass spectroscopy has been carried out, that involves the production of deeply bound states of a hadron-nucleus system. The formation of such objects has been investigated theoretically and the predicted bound states of kaon and nucleons are expected to have narrow decay widths, large binding energies and also a high density. Experimentally, direct reactions using kaon beams have been studied at KEK and at Frascati, ppnK-,pnnK-, ppK- states have been obseverd. The available data are far from being conclusive and more experiments are needed. In particular, we plan within the next two years a serie of exclusive measurements to study the production of such states in proton induced and heavy ion reactions. The theoretical predictions, the so far available results and the future experiments planned at SIS18 at GSI will be discussed. This programm is supported as Young Investigator Group by the HGF.
