DESCRIPTION:Although the Lambda(1405) resonance is known for several years
 \, its structure is still a topic of investigation. A detailed study of th
 e line shape of this resonance requires a variety of measured reactions wi
 th high statistic\, as the line shape of the Lambda(1405) turns out to be 
 not compatible with any standard form of resonances. The state of the art 
 is to treat this resonance in a coupled channels approach\, describing it 
 as a molecular state of a meson and a baryon. To verify these complex theo
 ries\, new experimental data arerequired. We have recentlz analyzed a p+p 
 run at 3.5 GeV\, measured with the High Acceptance Di- Electron Spectromet
 er (HADES). The Lambda(1405) could be reconstructed in all its three decay
  channels Sigma+pi-\, Sigma-pi+ and Sigma0pi0. The three different line sh
 apes can be compared to each other in order to investigate the dependence 
 of the line shape on the production and decay mechanism.\n\nhttps://indico
