Abstract:
Covariant propagators and complete vertices for spin J bosons with conserved currents for all J are worked out. These explicit propagators have been given before (Fronsdal, Durand), but the nontrivial derivation has heretofore been lacking or too cryptic. Our complete vertices, which are new to our knowledge, involve an apt set of form factors modelled on the electromagnetic ones. The strongly absorbed one spin J boson-exchange helicity amplitudes are given. The main application of these results is in realistic models, with explicit J-plane singularities, of the nondiffractive component of two hadron reaction amplitudes. The paper is presented as a useful tool and compendium for workers in this field.
