“…Information of these YN interactions at finite baryon density can be achieved in studies of hypernuclei [14,15,16] in reactions induced by mesons (π-and K-beams), by high-energy (anti)protons and heavy-ions, and by electro-production [18,19]. Recently, the FOPI [20] and HypHI [21] Collaborations at GSI have performed experiments on single-Λ hypernuclei with the analysis being still in progress.…”

We investigate for the first time the influence of hyperon-nucleon (YN) interaction models on the strangeness dynamics of antiproton- and $\Xi$-nucleus interactions. Of particular interest is the formation of bound multi-strangeness hypermatter in reactions relevant for \panda. The main features of two well-established microscopic approaches for YN-scattering are first discussed and their results are then analysed such that they can be applied in transport-theoretical simulations. The transport calculations for reactions induced by antiproton beams on a primary target including also the secondary cascade beams on a secondary target show a strong sensitivity on the underlying YN-interaction. In particular, we predict the formation of $\Xi$-hypernuclei with an observable sensitivity on the underlying $\Xi$N-interaction. We conclude the importance of our studies for the forthcoming research plans at FAIR.Comment: 13 pages, 5 figures. Accepted for publication in Physics Letters

“…According to the PANDA proposals, multi-strangeness bound hypermatter is supposed to be created in a two-step process through the capture of cascade particles (Ξ) -produced in primary antiproton-induced reactions -on secondary targets. Also theoretical investigations have been started recently [14,15,16,17].…”

“…On the theory side, major activities in this direction are being made by the Frankfurt-Mainz collaboration [29,30] and our own investigations. In a series of paper [24][25][26][27][28] we have been studying hyperon and hypernuclear production in proton and antiproton-induced reaction and in heavy ion collisions leading to fragmentation into light hypernuclei. In [28] we have for the first time investigated the role and possible observable effects of different YN-interaction models on the strangeness dynamics of hadron-induced reactions.…”

The production of strangeness on the nucleon and hyperon and hypernuclear production in heavy ion collisions at relativistic energies and in antiproton annihilation on nuclei is discussed. The reaction process is described by transport theory with focus on S = −2 channels and a comparison of different model interactions. The interactions of hyperons in nuclear matter is investigated in a novel SU (3) approach. An outlook to the S = −3 sector and Ω − physics is given.

“…The hyperon-nucleon interaction is not yet fully understood for the entire baryon octet and decuplet. However, it is better fixed in the S=-1 sector from studies on single-Λ hypernuclei [59,60,61,62,63,64,65,66,67,68] and from Λ (and Σ) production in reactions induced by hadrons and heavy-ions [54,69,70,71]. The free hyperon-nucleon interaction in the S=-1 channels has been investigated in detail within one-boson-exchange (OBE) approaches [72,73,74].…”

“…We have investigated in the past the formation and production mechanisms of hyperons [52], fragments [53] and hyperfragments [54,55] in reactions induced by heavy-ions, protons and antiprotons. Recently the role of the multi-strangeness hyperon-nucleon interaction (S = −2) has been explored in detail [56].…”

We discuss in detail the formation and propagation of multi-strangeness particles in reactions induced by hadron beams relevant for the forthcoming experiments at FAIR. We focus the discussion on the production of the decuplet-particle Ω and study for the first time the production and propagation mechanism of this heavy hyperon inside hadronic environments. The transport calculations show the possibility of Ω-production in the forthcoming PANDA -experiment, which can be achieved with measurable probabilities using high-energy secondary Ξ-beams. We predict cross sections for Ω-production. The theoretical results are important in understanding the hyperon-nucleon and, in particular, the hyperon-hyperon interactions also in the high-strangeness sector. We emphasize the importance of our studies for the research plans at FAIR.
