We present a new particle model that generalize for constant curvature space an infinite spin particle in flat space. The model is described by commuting Weyl spinor additional coordinates. It proved that such a model is consistent only in external g

We construct a Lagrangian that describes the dynamics of a six-dimensional free infinite (continuous) spin field in 6D Minkowski space. The Lagrangian is formulated in the framework of the BRST approach to higher spin field theory and is based on a s

We develop a complete off-shell Lagrangian description of the free 4D,N=1 supersymmetric theory of infinite spin. Bosonic and fermionic fields are formulated in terms of spin-tensor fields with dotted and undotted indices. The corresponding Lagrangia

Abstract We present the explicit superfield realizations of the hidden SU(4) and O(5) R-symmetries in 4D, N $$ \mathcal{N} $$ = 4 and 5D, N $$ \mathcal{N} $$ = 2 supersymmetric Yang-Mills theories in the harmonic superspace approach. The R-symmetry t

We construct massless infinite spin irreducible representations of the six-dimensional Poincaré group in the space of fields depending on twistor variables. It is shown that the massless infinite spin representation is realized on the two-twistor fi

We consider a massless higher spin field theory within the BRST approach and construct a general off-shell cubic vertex corresponding to irreducible higher spin fields of helicities s1,s2,s3. Unlike the previous works on cubic vertices, which do not

We continue studying 6D,N=(1,1) supersymmetric Yang-Mills (SYM) theory in the N=(1,0) harmonic superspace formulation. Using the superfield background field method we explore the two-loop divergences of the effective action in the gauge multiplet sec

We propose a description of manifestly supersymmetric continuous spin representations in 4D,N=1 Minkowski superspace at the level of equations of motions. The usual continuous spin wave function is promoted to a chiral or a complex linear superfield

We give an explicit component Lagrangian construction of massive higher spin on-shell N=1 supermultiplets in four-dimensional Anti-de Sitter space AdS4. We use a frame-like gauge invariant description of massive higher spin bosonic and fermionic fiel

We construct N=2 supersymmetric low-energy effective action of 5D,N=2 supersymmetric Yang–Mills (SYM) theory in 5D,N=1 harmonic superspace. It is obtained as a hypermultiplet completion of the leading WlnW-term in the N=1 SYM low-energy effectiv
