Abstract
A novel interest in the study of the Lambda(1405) has been recently outed. Indeed the composite nature of the Lambda(1405) as an overlap of a pi Sigma and K- p poles is not fully understood yet, especially as far as the contributing strength of the two poles to the total resonance is concerned. The study of the spectral shape of the Lambda(1405) extracted from the (Sigma pi)(0) spectra produced via different reactions can provide the necessary information to disentangle the complicated structure of this resonance. We present our analysis strategy to extract these information from p+p at 3.5 GeV collisions using the HADES spectrometer.
