THE BATHE-SALPETER EQUATION FOR SPIN-1 PARTICLES

The develop here the general treatment of the Bethe-Salpeter equation for the bound stale of two spin-1 particles interacting through an ele ctromagnetic interaction. The treatment here, which can be generalized to strong interactions, combines the two-component approach utilised previously by the author in conjunction with spontaneous symmetry brea king. This is done by using a Lagrangian having SU(2) x U(1) symmetry (without fermions) and their choosing the 't Hooft gauge. In this way, a renormalizable theory for the interaction of two spin-1 particles v ia an electromagnetic interaction is ensured.
