Description
In heavy ion collisions at beam energies of 1-2 AGeV, strangeness production can be observed below its elementary production threshold.
In April and May 2012, 7.3 billion Au(1.23 GeV per nucleon)+Au collisions have been recorded by the HADES detector, installed at the Helmholtzzentrum fuer Schwerionenforschung (GSI) in Darmstadt, Germany. In this collision system the weakly decaying strange hadrons $K^{0}_{s}$ and $\Lambda$ were measured and can be reconstructed. In order to draw conclusions on strangeness production mechanisms in heavy ion collisions the yields can be compared to non-strange particle production, i.e. charged pions.
In this contribution preliminary particle spectra of $\Lambda$ hyperons and $K^{0}_{s}$ mesons measured in these collisions are presented.
