Anotace	The resonance CS were determined from the one-pion channels for Delta(1232) and N(1440) (1.25 GeV) as well as further Delta and N* resonances up to 2 GeV/c(2) for the 3.5 GeV data. The data at 1.25 GeV energy were also analysed within the framework of the partial wave analysis together with the set of several other measurements at lower energies. The obtained solutions provided the evolution of resonance production with the beam energy, showing a sizeable non-resonant contribution but with still dominating contribution of Delta(1232)P-33. In the case of 3.5 GeV data, the study of the ppe(+)e(-) channel gave the insight on the Dalitz decays of the baryon resonances and, in particular, on the electromagnetic transition form-factors in the time-like region. We show that the assumption of a constant electromagnetic transition form-factors leads to underestimation of the yield in the dielectron invariant mass spectrum below the vector mesons pole. On the other hand, a comparison with various transport models shows the important role of intermediate rho production, though with a large model dependency. The exclusive channels analysis provides new stringent restrictions on the parameterizations used in the models.
