Abstract

The results of an analysis are presented of some recent data on the reactions e+eπ+ππ+πe^+e^-\to\pi^+\pi^-\pi^+\pi^-, e+eπ+ππ0π0e^+e^-\to\pi^+\pi^-\pi^0\pi^0 with the subtracted ωπ0\omega\pi^0 events, e+eωπ0e^+e^-\to\omega\pi^0, e+eηπ+πe^+e^-\to\eta \pi^+\pi^-, e+eπ+πe^+e^-\to\pi^+\pi^-, Kpπ+πΛK^-p\to\pi^+\pi^-\Lambda, the decays J/ψπ+ππ0J/\psi\to\pi^+\pi^-\pi^0, tauνtauπ+πππ0tau^-\to\nu_tau\pi^+\pi^-\pi^-\pi^0 tauντωπtau^-\to\nu_\tau\omega\pi^-, upon taking into account both the strong energy dependence of the partial widths on energy and the previously neglected mixing of the ρ\rho type resonances. The above effects are shown to exert an essential influence on the specific values of masses and coupling constants of heavy resonances and hence are necessary to be accounted for in establishing their true nature.
