Aspects of the gauge boson-gaugino mixing in a supersymmetric scenario with Lorentz-symmetry violation

Abstract

We write down an $\mathcal{N}=1$ supersymmetric extension for non-Abelian gauge theories in ($1+3$) dimensions with a Lorentz- and $CPT$-violating term of the Carroll-Field-Jackiw type. By including effects of the background (supersymmetric) fermion bilinears that accompany Lorentz-symmetry violation in a Carroll-Field-Jackiw scenario, we investigate both the gauge boson and gaugino dispersion relations in order to compute their respective masses in terms of the background structures. Such results open up a potential path towards a possible mechanism for gaugino-gauge boson conversion, an analog of the Primakoff effect, induced here not by an external magnetic field, but instead by the (Majorana) fermionic sector of the supersymmetry multiplet in the backstage of the Lorentz-symmetry violation.
