Carroll-Field-Jackiw term in a massless Rarita-Schwinger model

High Energy Physics - Theory 2025-03-26 v2

Abstract

We consider the massless Rarita-Schwinger (RS) LV QED. In this theory, we introduce the gauge fixing to obtain the propagator for the RS field, and calculate the Carroll-Field-Jackiw term, which turns out to be finite and ambiguous, and only in one calculation scheme, based on the nonlinear gauge framework, the gauge independence of the result is achieved.
