We present an analysis of the {Lambda}(1405){yields}{Sigma}{sup {+-}}{pi}{sup {+-}} decay in p+p reactions at 3.5 GeV kinetic beam energy. The data were taken with the High Acceptance Di-Electron Spectrometer (HADES). The extraction of the {Lambda}(1405) signal was achieved by an effective background suppression combined with a quantitatively precise determination and identification of the remaining background sources. The different techniques, used for this analysis, are presented in this work.
