【 摘 要 】

Preliminary results on the production of weakly decaying strange hadrons are reported for collisions of Au+Au at 1.23 AGeV beam energy studied with the HADES detector at GSI in Darmstadt. At this collision energy all strange particles are created below their elementary threshold. The reconstruction of the investigated particles (i.e. Λ and K0s) via the topology of their charged decay products (V0reconstruction) is presented in detail. From the corrected yields of Λ and K0sthe ratio K0S/Λcan be calculated and included into a statistical model fit.
