dc.title Baryon resonance production and dielectron decays in proton-proton collisions at 3.5 GeV pl
dc.type JournalArticle pl
dc.abstract.en 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 \rightarrow np\pi^{+} and pp \rightarrow pp\pi^{0} as well as pp \rightarrow 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 \rightarrow 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 ρ 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. pl
