Nuclear systems with two units of strangeness are still poorly known despite their importance for many strong interaction phenomena. Stored antiprotons beams in the GeV range represent an unparalleled factory for various hyperon-antihyperon pairs. Their outstanding large production probability in antiproton collisions will open the floodgates for a series of new studies of systems which contain two or even more units of strangeness. For the first time, high resolution gamma-spectroscopy of doubly strange nuclei will be performed, thus complementing measurements of ground state decays of double hypernuclei at J-PARC or possible decays of particle unstable hypernuclei in heavy ion reactions. High resolution spectroscopy of multistrange Cascade-atoms are feasible and even the production of Omega-atoms will be within reach. The latter might open the door to the s=3 world in strangeness nuclear physics, by the study of the hadronic Omega-nucleus interaction. For the first time it will be possible to study the behaviour of anti-Cascade in nuclear systems under well controlled conditions.

Hyperon production and the study of their properties is an important part of the physics programme of the future PANDA experiment at FAIR. Antihyperon-hyperon pairs will be produced in antiproton-proton collisions through the annihilation of at least one light antiquark-quark (u,d) pair and the creation of a corresponding number of antiquark-quark ss pairs. By measuring the decay products of the hyperons, spin observables such as the polarisation can be measured. Many hyperons have a long life-time which give rise to final state particles originating from displaced vertices. A pattern recognition algorithm using information from the PANDA Straw Tube Tracker is extended to reconstruct not only the transversal, but also the longitudinal components of charged tracks. A Hough transform and a path finding method as tools to extract the longitudinal components is being developed.

Stored antiprotons beams in the GeV range represent a unparalleled factory for hyperon-antihyperon pairs. Their outstanding large production probability in antiproton collisions will open the floodgates for a series of new studies of strange hadronic systems with unprecedented precision. The behaviour of hyperons and – for the first time – of antihyperons in nuclear systems can be studied under well controlled conditions. The exclusive production of Lambda-antiLambda and Sigma-antiLambda pairs in antiproton-nucleus interactions probe the neutron and proton distribution in the nuclear periphery and will help to sample the neutron skin. For the first time, high resolution gamma-spectroscopy of doubly strange nuclei will be performed, thus complementing measurements of ground state decays of double hypernuclei with mesons beams at J-PARC or possible decays of particle unstable hypernuclei in heavy ion reactions. High resolution spectroscopy of multistrange Cascade atoms are feasible and even the production of Omega-atoms will be within reach. The latter might open the door to the |s|=3 world in strangeness nuclear physics, by the study of the hadronic Omega-nucleus interaction and the very first measurement of a spectroscopic quadrupole moment of a baryon which will be a benchmark test for our understanding of hadron structure.
