Abstract

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.
