Abstract
We present the exclusive analysis of the reactions p_s16p _s13_s178594_s19 Y _s16 _s13_s17916_s19_s16_s16/(p _s16 _s13_s17960_s19_s16) _s16 K0, where Y stands for the _s13_s17923_s19 or _s13_s17931_s190 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(p_s13_s17960_s19_s16_s13_s17960_s19_s16_s13_s17960_s19_s13_s178722_s19), where we can separate the _s13_s17923_s19 from the _s13_s17931_s190 channel. From a Monte Carlo simulation of possible reactions we see contributions also by the reactions p _s16 p _s13_s178594_s19 _s13_s17931_s19_s16/_s13_s17931_s19(1385)_s16 _s16 p _s16 K0. The ongoing analysis should provide exclusive cross sections of the mentioned reactions and their angular distributions.
