Λ⁰ and K_S⁰ Production in Au+Au Collisions at 1.23A GeV in HADES — •Simon Spies for the HADES collaboration — Goethe-Universität Frankfurt

We use a high statistic data sample of 7.3 × 10⁹ recorded Au(1.23A GeV)+Au events to investigate Λ⁰ baryon and K_S⁰ meson production below their free nucleon nucleon threshold. These hadrons are being reconstructed using their weak decay topologies that are being recognized with the help of an artificial neural network. We calculate kinematic distributions in transverse and logitudinal direction of these hadrons and put them in context with phenomenological models.
