On the photon mass generation in Rarita-Schwinger QED

Abstract

This work examines the dynamical mass generation for the photon in Rarita-Schwinger QED. We focus our attention on the cases of $\omega =2,3$ dimensional spacetime. In these frameworks, it is well known that in the usual QED, the photon field (dynamically) acquires a gauge invariant mass (the Schwinger and Chern-Simons mass, respectively). We wish to scrutinize this phenomenon in terms of the Rarita-Schwinger fields. The presence of higher-derivative terms is shown as the leading contributions to the $1$PI function $⟨AA⟩$ at one-loop order. We study the pole structure of the photon's complete propagator to unveil the main effects of the Rarita-Schwinger fields on the photon's mass. In addition, we present some remarks about the renormalizability of this model (in different dimensions) due to the presence of higher-derivative corrections at one-loop.
