"We report on baryon resonance production and decay in proton-proton collisions at a kinetic energy of 3.5 GeV based on data measured with HADES. The exclusive channels pp -> np pi(+) and pp -> pp pi(0) as well as pp -> ppe(+)e(-) are studied simultaneously for the first time. The invariant masses and angular distributions of the pion-nucleon systems were studied and compared to simulations based on a resonance model ansatz assuming saturation of the pion production by an incoherent sum of baryonic resonances (R) with masses < 2 GeV/c(2). A very good description of the one-pion production is achieved allowing for an estimate of individual baryon resonance production cross sections which are used as input to calculate the dielectron yields from R -> pe(+)e(-) decays. Two models of the resonance decays into dielectrons are examined assuming a point-like RN gamma* coupling and the dominance of the rho meson. The results of model calculations are compared to data from the exclusive ppe(+)e(-) channel by means of the dielectron and pe(+)e(-) invariant mass distributions."@en .
