The strangness S=-2 nuclear physics setup at PANDA: status and prospects — Patrick Achenbach, Sebastian Bleser, Michael Bölting, Josef Pochodzalla, Birte Sauer, Falk Schupp, and •Marcell Steinen for the PANDA collaboration — Helmholtz Institute Mainz, Johannes Gutenberg University, 55099 Mainz
PANDA at FAIR will address the physics of strange baryons with S=-2 in nuclei by several novel and unique measurements. In particular, PANDA will extend the studies on double hypernuclei by performing high resolution γ-spectroscopy of these nuclei for the first. Furthermore, PANDA offers the unique possibility to search for X-rays from very heavy hyperatoms as e.g. Ξ−-208Pb. This will complement experiments at J-PARC which attempt to measure X-rays in medium-heavy nuclei. Finally, the exclusive production of hyperon-antihyperon pairs close to their production threshold in p - nucleus collisions offers a unique and hitherto unexplored opportunity to elucidate the behaviour of antihyperons in nuclei.
In this contribution we will review the strangness S=−2 nuclear physics program at PANDA with emphasis on the hyperatom part. We will also present the design of the detection system and the current status of the prototype. Test results of the various detector components will be discussed.
