Production of Σ±π∓pK+ in p+p reactions at 3.5 GeV beam energy

We study the production of Σ±π∓pK+ particle quartets in p + p reactions at 3.5 GeV kinetic beam energy. The data were taken with the HADES experiment at GSI. This report evaluates the contribution of resonances like Λ(1405), Σ(1385)0, Λ(1520), Δ(1232), N⁎ and K⁎0 to the Σ±π∓pK+ final state. The resulting simulation model is compared to the experimental data in several angular distributions and it shows itself as suitable to evaluate the acceptance corrections properly.
