Hard meson calculation of sigma pi pi , A sigma pi and sigma AA vertices
The low-energy theorems on the phi A/sub mu /A/sub nu / vertex following from current algebra and from the dimensional properties of the various components of the axial vector current A/sub mu / and of its divergence delta mu A/sub mu / are extended to finite momenta assuming of the energy momentum...
