Abstract
The amplitudes obtained from the effective chiral Lagrangian with anomalous terms based on hidden local symmetry are applied to the evaluation of the partial widths of the decay {omega} {yields} 2{pi}{sup +}2{pi}{sup -}{pi}{sup 0} and {omega} {yields} {pi}{sup +}2{pi}{sup -}3{pi}{sup 0}. Combining the Okubo-Zweig-Iizuka rule applied to the five-pion final state with the Adler condition of vanishing of the amplitude at the vanishing of four-momentum of any final pion in chiral limit, the {phi} {yields} 2{pi}{sup +}2{pi}{sup -}{pi}{sup 0} and {phi} {yields} {pi}{sup +}{pi}{sup -}3{pi}{sup 0} decay amplitudes are also calculated. The partial widths of the above decays are evaluated, and the resonance excitation curves in e{sup +}e{sup -} annihilation are obtained, assuming reasonable particular relations among the free parameters characterizing the anomalous terms of the Lagrangian. The evaluated branching ratios Br{sub {phi}} {sub {yields}} {sub {pi}}{sub {sup +}}{sub {pi}}{sub {sup -}}{sub 3{pi}}{sub {sup 0}} {approx} 2 x 10{sup -7} and Br{sub {phi}} {sub {yields}} {sub 2{pi}}{sub {sup +}}{sub 2{pi}}{sub {sup -}}{sub {pi}}{sub {sup 0}} {approx} 5 x 10{sup -7} are such that with the luminosity L=500 pb{sup -1} attained at DA{phi}NE {phi} factory one may already possess about 1340 events of the decay {phi} {yields} 5{pi}.
