Many pion decays of ρ(770) and ω(782) mesons in chiral theory -: art. no. 056011

The decays rho(770) --> 4 pi and omega(782) --> 5 pi are considered in derail in the approach based on the Weinberg Lagrangian obtained upon the nonlinear realization of chiral symmetry, added with the term induced by the anomalous Lagrangian of Wess and Zumino. The partial widths and excitation curves of the decays rho(0) --> 2 pi(+)2 pi(-), pi(+)pi(-)2 pi(0), rho(+/-) --> 2 pi(+/-)pi(-/+)pi(0), rho(+/-) --> pi(+/-)3 pi(0) are evaluated for e(+)e(-) annihilation, photoproduction, and tau lepton decays. The results of the calculations are compared with the recent CMD-2 data on the decay rho(0)-->2 pi(+)2 pi(-) observed in the e(+)e(-) annihilation. The omega --> 5 pi decay widths and excitation curves in e(+)e(-) annihilation are obtained. The angular distributions for various combinations of the final pions in the decays rho --> 4 pi and omega --> 5 pi are written. The perspectives of the experimental study of the above decays in e(+)e(-) annihilation, tau lepton decays, and photoproduction are discussed.
