TL;DR
This paper explores vacuum polarization effects in the Rarita-Schwinger model with spin-3/2 fields under Very Special Relativity, using the Mandelstam-Leibbrandt prescription in the SIM(2) limit.
Contribution
It introduces a detailed analysis of the Rarita-Schwinger model in VSR, applying specific regularization techniques and focusing on both massive and massless cases.
Findings
Vacuum polarization effects are characterized in the VSR framework.
The Mandelstam-Leibbrandt prescription effectively evaluates one-loop integrals.
Results highlight differences from standard Lorentz-invariant models.
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.
