Vector Meson Decays in Unitary Symmetry

Katsumi Tanaka

Open publisher page 13 citations

Abstract

The relations among the amplitudes for the decays of a vector meson into two pseudoscalar mesons and a photon and among those for decays into two pseudoscalar mesons and $N$ photons are derived by means of a convenient method based on the symmetry properties of the Lagrangian. These derivations are preceded by the rederivations of the relations among the amplitudes for the decays of a vector meson into two pseudoscalar mesons and among those for the decays into a pseudoscalar meson and $N$ photons.
