Abstract

We present the exclusive analysis of the reactions p+p → Y + Δ++/(p + π⁺) + K⁰, where Y stands for the Λ or Σ⁰ hyperon. The proton-proton measurement was performed with the HADES setup at GSI, Darmstadt, at a kinetic beam energy of 3.5 GeV. A dedicated sideband technique allows to reproduce the non-strange background and its kinematics in the selected data sample. Therefore, it is possible to obtain the background subtracted missing mass distribution MM(pπ⁺π⁺π^-), where we can separate the Λ from the Σ⁰ channel. From a Monte Carlo simulation of possible reactions we see contributions also by the reactions p + p → Σ⁺/Σ(1385)⁺ + p + K⁰. The ongoing analysis should provide exclusive cross sections of the mentioned reactions and their angular distributions.
