Query: Many Facets of Strangeness Nuclear Physics with Stored Antiprotons   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 behavior of
hyperons and -- for the first time -- of antihyperons in nuclear systems can be
studied under well controlled conditions. The exclusive production of
$\Lambda\bar{\Lambda}$ and $\Sigma^-\bar{\Lambda}$ 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 $\Xi$-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.
