RESONANCES IN THE ISOVECTOR P WAVE OF pi pi SCATTERING
Original language description
Parameters of rho-like resonances are obtained in the multichannel analysis of the pi pi-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 rho(1250) meson and showed that the simultaneous existence of the rho(1450) and rho(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 interpretedas the rho sigma channel.
