Search for the hypertriton via its three-body-decay — •Holger Huck for the HADES collaboration — Institut für Kernphysik, Goethe-Uni, Frankfurt, Deutschland

We use Au+Au heavy ion collisions at 1.23A GeV to search for Λ3H-hypernuclei via it’s three-body-decay in d, p and π. After particle identification, we apply topological restrictions based on the weak decay to find a signal in the invariant mass spectrum. The uncorrelated combinatorical background is estimated with the mixed-event-method. Because of the similar Λ-decay in p and π, there is a source of correlated background which has to be taken into account. With the help of simulation we introduce an invariant mass cut on combined p and π to seperate the correlated background from free Λ-hyperon from the Λ3H-sample.
