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 Ekin = 3.5 GeV measured with HADES. Upper and lower limits have been determined for the ratio . 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.

Abstract
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 Ekin = 3.5 GeV measured with HADES. Upper and lower limits have been determined for the ratio . 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.
