Λ and KS0 Reconstruction in Au+Au Collisions at 1.23A GeV with HADES — •Timo Scheib for the HADES collaboration — Goethe-Universität, Frankfurt

We use a high statistic data sample of 7.3x109 recorded Au(1.23A GeV)+Au events to investigate Λ baryon and KS0 meson production below their free nucleon-nucleon threshold. Both particles have never been observed below their NN threshold in heavy-ion collisions before.
We highlight details of the analysis procedure such as event selection, particle identification and topological cuts on the decay kinematics before presenting and discussing the transverse energy spectra as well as production yields and their rapidity dependence.

This work has been supported by BMBF (05P12RFGHJ, 05P15RFFCA), GSI and HIC for FAIR.
