The production mechanism of the Σ0 was investigated via the exclusive reaction pp → pK+Σ0 at a beam energy 3.5 GeV with the HADES detector. The preliminary value of the extracted total production cross section is found to be σ(pK+Σ0)[μb] = 17.7 ± 1.7(stat) ± 1.6(syst). The dynamics of the reaction pp → pK+Σ0 was investigated by studying the angular distributions in the center-of-mass, Gottfried-Jackson and helicity frames. The angular distributions in the center-of-mass frame supports the pion exchange mechanism. Furthermore, the helicity angular distributions are highly non-isotropic, which is a clear indication of resonant production component.
