Abstract
We present an analysis of the hyperons Λ(1405) and Σ(1385) + for p+p reactions at 3.5 GeV kinetic beam energy. The data were taken with the High Acceptance Di-Electron Spectrometer (HADES). A Λ(1405) signal could be reconstructed in both charged decay channels Λ(1405)→Σ± π ∓ . The obtained statistics of the Σ(1385) + signal allows also differential studies.
