Аннотация

The Bethe-Salpeter equation for massive spin-1 particles is considered. The amplitude for the scattering of spin-1 particles is expanded in relativistically invariant tensors. The coefficients in the transformation of helicity amplitudes into invariant functions for the scattering amplitude are found. The set of integral equations for these invariant functions is derived, and the partial-wave expansion of this set is performed. An equivalent set of integral equations for partial-wave helicity amplitudes is presented.
