We study the general non-minimally coupled charged massive spin 3/2 model both for its low energy phenomenological properties and for its unitarity, causality and degrees of freedom behavior. When the model is viewed as an effective theory, its parameters (after ensuring the correct excitation count) are related to physical characteristics, such as the magnetic moment g factor, by means of low energy theorems. We also provide the corresponding higher spin generalization. Separately, we consider both low and high energy unitarity, as well as the causality of our models. None (including truncated N = 2 supergravity) is free of the minimal model’s acausality.
