Production of Sigma(+/-)pi(-/+)pK(+) in p plus p reactions at 3.5 GeV beam energy
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.
