Three-body decays of ${\pi }_2(1670)$ and ${\rho }_3(1690)$ via the Sill distribution

Abstract

We present the three-body decays for the resonances ${\pi }_2(1670)$ and ${\rho }_3(1690)$. We use an effective model based on the flavor symmetry and have assumed the Sill distribution for describing the lie-shape of intermediate unstable resonances. The vector-pseudoscalar meson decay channel is considered as an intermediate step to explain the decay of three-pseudoscalar meson channels.
