- Abstract
Parameters of ρ-like resonances are obtained in the multichannel analysis of the ππ-scattering data below 1.9 GeV and a possible classification of the resonance states is discussed. In the 3-channel analysis, we confirmed the existence of the ρ(1250) meson and showed that the simultaneous existence of the ρ(1450) and ρ(1250) mesons does not contradict the data. The analysis indicates an importance of presence of some effective channel with the threshold at 1512 MeV, which might be interpreted as the ρσ channel.
