The aim of the present analysis is to determine the relative production cross sections of the Λ(1405) and Σ(1385) 0 resonances in p+p collisions at E kin = 3. 5 GeV measured with HADES. Upper and lower limits have been determined for the ratio σ(Σ(1385) 0+p+K +)/σ(Λ(1405)+p+K +)=0.76 +0.54 -0.26. The knowledge of this ratio is an essential input for the analysis of the decay Λ(1405)→Σ ±π ∓, where an unambiguous separation of the Λ(1405) and Σ(1385) 0 signals is not possible. © 2012 Springer Science+Business Media B.V.
