I=1 heavy resonances in e+e- annihilation, in the decay J/ψ→π+π-π0, and in the reaction K-p→π+π-Λ

Data on the reactions e+e-→π+π-, e+e-→ωπ0, e+e-→π+π-π+π-, e+e-→π+π-π0π0, e+e-→ηπ+π-, J/ψ→π+π-π0, and K-p→π+π-Λ are analyzed with allowance for the energy dependence of partial widths and for the mixing of the ρ-type resonances, which was previously disregarded. It is shown that, for heavy resonances, this mixing significantly affects specific mass values and coupling constants; hence, it must be taken into account in studying their nature
