Taming of divergences in a unitary model of massive fermions, vectors and scalars Original Research Article

We consider a massive vector field, interacting through three-field interactions with a massive scalar and spinor field, in a unitary model. There are divergences that cannot be removed by introduction of counter terms into the Lagrangian. It is shown that it is possible to tame many of them and to remove the remaining divergences by appropriate choices of the coupling constants.
