There are three self-dual models of massive particles of helicity+ 2 (or-2) in D= 2+ 1. Each
model is of first, second, and third-order in derivatives. Here we derive a new self-dual …

We suggest a new spin-4 self-dual model (parity singlet) and a new spin-4 parity doublet in
D= 2+ 1. They are of higher order in derivatives and are described by a totally symmetric …

Abstract The Fierz-Pauli (FP) free field theory for massive spin-2 particles can be extended,
in a spacetime of (1+ 2) dimensions (3D), to a generally covariant parity-preserving …

We present here a relationship among massive self-dual models for spin-3 particles in D=
2+ 1 via the Noether gauge embedment (NGE) procedure. Starting with a first-order model …

We have demonstrated that the fermionic part of the so called “New Topologically Massive
Supergravity”, which is of third order in derivatives, is classically equivalent to self-dual …

In D= 2+ 1 dimensions there are two dual descriptions of parity singlets of helicity±1, namely,
the self-dual model of first order (in derivatives) and the Maxwell-Chern-Simons theory of …

Here we present the “soldering” of opposite helicity states of a spin-3 particle, in D= 2+ 1,
into one parity doublet. The starting points may be either the sixth-or fifth-order (in …

We construct a supersymmetric formulation of three-dimensional linearized new massive
gravity without introducing higher derivatives. Instead, we introduce supersymmetrically a …

The soldering procedure has been for the first time generalized to the case of spin-3/2
fermionic theories. We have demonstrated that the fermionic part of the so-called “New …

In D= 2+ 1 dimensions, elementary particles of a given helicity can be described by local
Lagrangians (parity singlets). By means of a “soldering” procedure, two opposite helicities …
