We construct the Lagrangian description of arbitrary integer higher-spin massless fields on
the background of the D-dimensional anti-de Sitter space. The operator constraints in …

A bstract We present, for the first time, the complete off-shell 4D,\(\mathcal {N}\)= 2 superfield
actions for any free massless integer spin s≥ 2 fields, using the\(\mathcal {N}\)= 2 harmonic …

We present a Lagrangian formulation for the free superspin-3 2 massive 4D, N= 1 superfield.
The model is described by a dynamical real vector superfield and an auxiliary real scalar …

Building on the superspace formulation for four-dimensional Script N= 2 matter-coupled
supergravity developed in [1], we elaborate upon a general setting for field theory in Script …

As a step towards formulating projective superspace techniques for supergravity theories
with eight supercharges, this work is devoted to field theory in five-dimensional N= 1 anti-de …

An action describing the dynamics of an infinite collection of massless integer spin fields
with spin s= 0, 1, 2, 3,... $\infty $ corresponding to totally symmetric Young tableaux …

For the gauge massless higher spin 4D, Script N= 1 off-shell supermultiplets previously
developed, we provide evidence of a twistor-like oscillator realization that is intrinsically …

The model of point particle in general external fields is considered and the generalized
equivalence principle is suggested identifying all backgrounds which give rise to equivalent …

The model of a point particle in the background of external symmetric tensor fields is
analyzed from the higher spin theory perspective. It is proposed that the gauge …

The N= 1 superfield formalism in four-dimensions is well formulated and understood, yet
there remain unsolved problems. In this thesis, superfield actions for free massless and …
