On the regularization of quantum electrodynamics induced by nonpolynomial Lagrangians

Our purpose in this paper is to analyse the coupling of a real massless scalar field with the interacting Dirac-Maxwell fields through a nonpolynomial factor which simulates the presence of %/-- g. We give a proof that no such a thing as a superpropagator appears and, as consequence, the removal of...

description Our purpose in this paper is to analyse the coupling of a real massless scalar field with the interacting Dirac-Maxwell fields through a nonpolynomial factor which simulates the presence of %/-- g. We give a proof that no such a thing as a superpropagator appears and, as consequence, the removal of infinities does not follow, at least in a straightforward manner, from the nonpolynomial character of the Lagrangian. The implied suggestion is that, if gravity plays a regularizing role in the theory, either its tensor character is essential for that purpose or the regularization is provided by other coupling.
