Physics of Hypernuclei - from FINUDA to PANDA — •O.N. Hartmann1, P. Gianotti1, J. Pochodzalla2, A. Sanchez Lorente2, T. Saito3, and C. Sfienti3,4 — 1INFN–LNF, Frascati, Italy — 2U Mainz, Germany — 3GSI, Darmstadt, Germany — 4U Catania, Italy
The FINUDA [1] experiment at the DAΦNE e+e−-collider (φ-factory, [2]) has completed its first data taking on hypernuclei produced by stopping K−-mesons from the φ decay in various target nuclei. The FINUDA apparatus performs studies on hypernuclear spectroscopy and the decay of hypernuclei.
The hypernuclei physics part of the PANDA [3] program at FAIR [4] will be an extension of this type of physics to double hypernuclei. This experiment uses the antiproton beam of HESR [4,3] on a primary heavy target producing a ΞΞ pair. The Ξ−-hyperon is stopped in a secondary target, captured into the atomic shell of the target nucleus and finally absorbed in the nucleus producing a ΛΛ pair. This will make the study of the strong interaction strength between Λ-hyperons possible, as well as the investigation of a possibly existing double strange six quark state (H-dibaryon).
In this contribution first results from FINUDA will be presented as well as an overview on the future plans in PANDA.
