Rarita-Schwinger model in Very Special Relativity

M. C. Araújo, J. Furtado, J. G. Lima, T Mariz

Abstract

In this work, we investigate vacuum polarization in the Rarita-Schwinger model within the framework of Very Special Relativity. We examine both massive and massless spin-3/2 fields coupled to the Maxwell field. The Mandelstam-Leibbrandt prescription is applied in order to evaluate the one-loop integrals, and we work within the SIM(2) limit.
