摘要
Pion beams are perfect tools to probe resonance excitations at a fixed energy. thus properties of baryonic resonances and their coupling channels can be studied. The HADES Collaboration performed a systematic scan around the second resonance region at four different pion beam momenta 0.656, 0.69, 0.748 and 0.8 GeV/c in pi(-)p reaction. The role of the N(1520) resonance in conjunction with the intermediate rho-meson production has been studied in the framework of a partial wave analysis. Preliminary results on exclusive channels with one pion (pi(-)p) and two pions (n pi(+)pi(-) and p pi(-)pi(0)) in the final state are presented.
