Abstract. We investigate the properties of multi-strangeness bound systems in in-medium reactions induced by hadron beams and discuss the role of the hyperon-nucleon interaction on the dynamical formation of double-Λ- and Ξ-hypernuclei. We found a considerable sensitivity of the in-medium hyperon interaction on the hypernuclear yields. Furthermore, we study the production mechanism of the decuplet Ω-baryon. Our results are relevant for the forthcoming P̅ANDA-experiment at FAIR and important to understand better the still less known hyperon-nucleon and hyperon-hyperon interactions in the high-strangeness sectors.
