Abstract

The general off mass-shell one-loop amplitude ta the termion triangle diagrams is calculated, in theories with γ5 couplings for spin-1 particles. Properties of the Bose symmetry and Ward identities for the couplings of neutral particles are investigated . The VVA and AAA triangle diagrams are obtained from our general form. All resulting amplitudes are consistent with Ward identities. The amplitude for the coupling of three identical spin-1 particles is given. This amplitude obeys Bose symmetry and Ward identities for anomaly free theory.
