A high-statistic data sample of Ar(1.76 AGeV)+KCl events recorded with HADES is used to search for a hypertriton signal. An upper production limit per centrality-triggered event of 1.04×10-3 on the 3σ level is derived. Comparing this value with the number of successfully reconstructed Λ hyperons allows to determine an upper limit on the ratio N3ΛH/NΛ which is confronted with statistical and coalescence-type model calculations. © Società Italiana di Física / Springer-Verlag 2013.
