In this work, we present two possible venues to accomodate the KF -type Lorentz-symmetry violating Electrodynamics in an N = 1-supersymmetric framework. A chiral and a vector superfield are chosen to describe the background that signals Lorentz-symmetry breaking. In each case, the K µνκλ -tensor is expressed in terms of the components of the background superfield that we choose to describe the breaking. We also present in detail the actions with all fermionic partners of the background that determine K µνκλ .

Background fermion condensates in a landscape dominated by global supersymmetry are reassessed in connection with a scenario where Lorentz symmetry is violated in the bosonic sector (actually, the photon sector) by a CPT-even k F term. An effective photonic action is discussed that originates from the supersymmetric background fermion condensates. Also, the photino mass emerges in terms of a particular condensate contrary to what happens in the case of k AF -violation. Finally, the interparticle potential induced by the effective photonic action is investigated and a confining profile is identified.
