Resonance Production and Decay in Proton and Pion Induced Collisions with HADES
Original language description
Resonance production and decay in proton-proton collisions at kinetic beam energies of 1.25 GeV and 3.5 GeV as well as r-p reactions at four different pion beam momenta (0.656, 0.69, 0.748 and 0,8 GeV/c) are investigated,lxclusive channels with one pion in the final state (ipm and pp71-1) in the pp collisions were put to extended studies based on various observables in the framework of a one pion exchange model and with solutions obtained within the framework of a partial wave analysis (PWA) of the Bonn-Gatchina group. In the case of the 3.5 GeV data, the study of the ppe+ e- channel gave insight on the dielectron production from 1f'' and A in the second and third resonance regions. We show that the measured dielectron invariant mass distribution cannot be explained by a point like resonance-y* coupling. Comparison with various transport models unravels the ambiguities of the descriptions and the important role of the intermediate p production. To tackle this problem a systematic investigation focused on the role of N(1520) production and decay in pion induced reactions on polyethylene and carbon targets,lirst results on exclusive channels with one pion (7-p), two pions (n7-'7-) and dileptons (ne(+)e(-)) in the final state are presented.
