Carroll-Field-Jackiw term in a massless Rarita-Schwinger model
arXiv:2410.01550 · doi:10.1016/j.physletb.2025.139408
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.
