Query: Chiral dynamics of many pion systems: the rho to 4 pi and omega to 5 pi
  decays   Based on the Weinberg lagrangian or, in a new language, the lagrangian of
hidden local symmetry added with the term induced by the anomalous lagrangian
of Wess and Zumino, the dynamics of the decays rho to 4 pi and omega to 5 pi is
considered. The excitation curves of rho resonance in its decay to 4 pi are
obtained for the first time. The comparison with recent CMD-2 data is given.
The partial widths of the decays omega to 2 pi^+ 2 pi^- pi^0 and omega to pi^+
pi^-3 pi^0 which can be measured on colliders with luminosity 10^{33}{cm
}^{-2}{s}^{-1} are evaluated for the first time.
