Testing chiral models of vector mesons in multipion decays of ρ(770) and ω(782)

Predictions of the models based on effective chiral Lagrangians of vector mesons ρ(770) and ω(782) are considered for such measurable quantities as the partial widths of various ρ → 4π and ω → 5π decays and their corresponding excitation curves. Analogous curves for the channel ρ? → (4π)? are obtained for τ lepton decays. The angular distributions for various combinations of the final pions from the ρ → 4π and ω → 5π decays in the e ⁺ e ^?-annihilation and photoproduction are also found. A simple method for the order-of-magnitude estimation of the partial widths based essentially on the threshold character of the above multipion decays is presented.
