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 (Σ(1385)0+p+K+)(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.
