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…

Gauge-invariant interaction of spin-(3/2) resonances

We show that the gauge-invariant coupling suggested by Pascalutsa removes non-pole terms from the spin-(3/2) propagator only for a specific choice of free parameter. For the general case, the problem

NEW SYMMETRY CURRENT FOR MASSIVE SPIN-3/2 FIELDS

We present several new results which will be of value to theorists working with massive spin-3/2 vector-spinor fields as found, for example, in low and intermediate energy hadron physics and also

A bstractIn this work we systematically study various aspects of spin-3/2 fields in a curved background. We mostly focus on a minimally coupled massive spin-3/2 field in arbitrary dimensions, and

Symmetry of massive Rarita-Schwinger fields

We derive the general Lagrangian and propagator for a vector-spinor field in d-dimensions and show that the physical observables are invariant under the so-called point transformation symmetry. Until

Dirac quantisation of a massive spin-3/2 particle coupled with a magnetic field

The canonical quantisation of the massive spin-3/2 field coupled with the external electromagnetic field is carried out by the use of Dirac's Hamiltonian method. It is shown that the quantisation can

g=2 as the natural value of the tree-level gyromagnetic ratio of elementary particles.

A natural'' electromagnetic coupling prescription is implemented at the Lagrangian level, different from the minimal one, and yields, for elementary particles of [ital arbitrary][minus][ital spin], a gyromagnetic ratio [ital g]=2 at the tree level.

Quantization of a Spin-3/2 Field Interacting with the Electromagnetic Field

Quantization of the Rarita-Schwinger field interacting with the internal (external) electro­ magnetic field is made by using the Dirac-Casalbuoni method. The generators of the Poincare group are

Broken Supersymmetry and Supergravity

We consider the supersymmetric Higgs effect, in which a spin-\textonehalf{} Goldstone fermion is transformed away by a redefinition of the supergravity fields and the spin-$\frac{3}{2}$ gauge field

Quantization of an interacting spin - 3 / 2 field and the Delta isobar

Quantization of the free and interacting Rarita-Schwinger field is considered using the Hamiltonian path-integral formulation. The particular interaction we study in detail is the

Consistent Supergravity with Complex Spin 3/2 Gauge Fields

A new theory of supergravity is constructed which is invariant under complex local supersymmetry transformations. This theory is obtained by coupling the massless spin- (3/2,1) multiplet of ordinary

Derivation of gauge invariance from high-energy unitarity bounds on the S matrix

A systematic search is made for all renormalizable theories of heavy vector bosons. It is argued that in any renormalizable Lagrangian theory high-energy unitarity bounds should not be violated in

Search for consistent interactions of the Rarita-Schwinger field

Bilinear, nonderivative couplings of the massive Rarita-Schwinger (RS) field are investigated. The most general coupling of this type involves 14 $\mathrm{SL}(2, C)$ irreducible tensors. Eleven of
