“…The electromagnetic interaction of massive spin-3/2 is an old problem. It has been studied by several authors [32,5,33,34,35,36,37]. Here we start with the Lagrangian for a free massive complex Rarita-Schwinger field:…”

We argue that the theory of a massive higher spin field coupled to electromagnetism in flat space possesses an intrinsic, model independent, finite upper bound on its UV cutoff. By employing the Stückelberg formalism we do a systematic study to quantify the degree of singularity of the massless limit in the cases of spin 2, 3, 3/2, and 5/2. We then generalize the results for arbitrary spin to find an expression for the maximum cutoff of the theory as a function of the particle's mass, spin, and electric charge. We also briefly explain the physical implications of the result and discuss how it could be sharpened by use of causality constraints.

“…Later, Velo and Zwanziger went on to show that the classical theory itself suffers from pathologies [96]. As already mentioned, this Velo-Zwanziger problem is very generic for interactions of massive HS fields [97][98][99][100][101][102][103][104][105][106]. It shows, contrary to what Fierz and Pauli might have anticipated, that neither the Lagrangian formulation does make the consistency of HS interactions automatic.…”

“…This pathology manifests itself in general for all charged massive HS particles with s > 1. It is quite challenging, field theoretically, to construct consistent interactions of massive HS particles since this problem persists for a wide class of non-minimal generalizations of the theory and also for other interactions [99][100][101][102][103][104][105][106]. The good news is that a judicious set of non-minimal couplings and/or additional dynamical degrees of freedom can actually come to the rescue [106][107][108][109][110].…”

A contribution to the collection of reviews Introduction to Higher Spin Theory edited by S. Fredenhagen, this introductory article is a pedagogical account of higher-spin fields and their connections with String Theory. We start with the motivations for and a brief historical overview of the subject. We discuss the Wigner classifications of unitary irreducible Poincaré-modules, write down covariant field equations for totally symmetric massive and massless representations in flat space, and consider their Lagrangian formulation. After an elementary exposition of the AdS unitary representations, we review the key no-go and yes-go results concerning higher-spin interactions, e.g., the Velo-Zwanziger acausality and its string-theoretic resolution among others. The unfolded formalism, which underlies Vasiliev's equations, is then introduced to reformulate the flat-space Bargmann-Wigner equations and the AdS massive-scalar Klein-Gordon equation, and to state the "central onmass-shell theorem". These techniques are used for deriving the unfolded form of the boundary-to-bulk propagator in AdS 4 , which in turn discloses the asymptotic symmetries of (supersymmetric) higher-spin theories. The implications for stringhigher-spin dualities revealed by this analysis are then elaborated.

In this work, we calculate the solutions of the Rarita-Schwinger equation with the inclusion of the electromagnetic interaction. Our gauge and coupling prescription choices lead to Dirac-type solutions. One of the consequences of our results is that all inconsistencies related to noncovariance and noncausality are avoided and the Landau level occupation of particles turns up to be quite different from the usual spin 1/2 particle system occupation numbers.
