In this paper, we formulate the Lorentz-breaking extension for the spin-3/2 field theory and couple it to the Abelian gauge field in a Lorentz violating (LV) manner. Next, we calculate the lower LV quantum corrections, that is, the Carroll-Field-Jackiw (CFJ) term, which, being superficially divergent, turns out to be finite but ambiguous, and also the higher-derivative CFJ term. Besides, we compute the aether term, being the lowest CPT-even LV term, involving the second order in the LV vector.

  1. On the photon mass generation in Rarita-Schwinger QED

    hep-th 2024-12 reject novelty 6.0 of 10

    The one-loop photon self-energy in Rarita-Schwinger QED is computed in 2, 3, and 4 dimensions, giving the Schwinger mass in 2D and higher-derivative-dominated pole structures in 3D.

  2. Bhabha-like scattering in the Rarita-Schwinger model at finite temperature

    hep-th 2024-12 reject novelty 4.0 of 10

    For a massive Rarita-Schwinger spin-3/2 fermion coupled to photons, the tree-level Bhabha-like differential cross-section is derived at finite temperature, with a claimed T squared high-temperature growth.
