We study the production of Sigma(+/-)pi(-/+)-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 Lambda(1405), Sigma(1385)(0), Lambda(1520), Delta(1232), N* and K*(0) to the Sigma(+/-)pi(-/+)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.

Abstract
We study the production of Sigma(+/-)pi(-/+)-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 Lambda(1405), Sigma(1385)(0), Lambda(1520), Delta(1232), N* and K*(0) to the Sigma(+/-)pi(-/+)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.
