A Gauge Field Theory for Continuous Spin Tachyons

We present a gauge field theory for unitary infinite dimensional tachyonic representations of the Poincar\'e group. It was obtained by a dimensional reduction from the gauge field theory for

Infinite Spin Fields in d = 3 and Beyond

In this paper, we consider the frame-like formulation for the so-called infinite (continuous) spin representations of the Poincare algebra. In the three-dimensional case, we give explicit Lagrangian

Unified formulation for helicity and continuous spin fermionic fields

A bstractWe propose a unified BRST formulation of general massless fermionic fields of arbitrary mixed-symmetry type in d-dimensional Minkowski space. Depending on the value of the real parameter the

Modified Wigner equations and continuous spin gauge field

In this paper, we first propose the bosonic (fermionic) modified Wigner equations for continuous spin particle (CSP). Secondly, starting from the (Fang-)Fronsdal-like equation, we will reach to the

Massless Infinite Spin (Super)particles and Fields

A new twistorial field formulation of a massless infinite spin particle is derived. We find a twistorial infinite spin field and derive its helicity decomposition. The twistorial equations of motion



Gauge theory formulations for continuous and higher spin fields

We consider a gauge theory action for continuous spin particles formulated in a spacetime enlarged by an extra coordinate recently proposed by Schuster and Toro. It requires one scalar gauge field

Continuous-spin particle field theory with helicity correspondence

We propose the first covariant local action describing the propagation of a single free continuous-spin degree of freedom. The theory is simply formulated as a gauge theory in a ``vector

1 — The wave functions, ψ, describing the possible states of a quantum mechanical system form a linear vector space V which, in general,. is infinite dimensional and on which a positive definite

Continuous spin representations of the Poincaré and super-Poincaré groups

We construct Wigner’s continuous spin representations of the Poincare algebra for massless particles in higher dimensions. The states are labeled both by the length of a spacelike translation vector

Massless Fields with Integer Spin

The Fierz-Pauli Lagrangian for massive particles with arbitrary integral spin s, first obtained by Hagen and Singh, is examined in the limit of vanishing mass. Unexpectedly, a considerable

Massless fields with half-integral spin

The Fierz-Pauli Lagrangian for massive particles with spin s = n + 1/2, n integer, is examined in the limit of vanishing mass. A considerable simplification occurs. The potential h is a

Continuous spin representations from group contraction

We consider how the continuous spin representation (CSR) of the Poincare group in four dimensions can be generated by dimensional reduction. The analysis uses the front-form little group in five

80 Years of Professor Wigner's Seminal Work "On Unitary Representations of the Inhomogeneous Lorentz Group"

It is perhaps the most fundamental principle of Quantum Mechanics that the system of states forms a linear manifold,1 in which a unitary scalar product is defined.2 The states are generally

Introduction to the Classical Theory of Higher Spins

We review main features and problems of higher spin field theory and flash some ways along which it has been developed over last decades.
