Abstract We study the off-shell structure of the two-loop effective action in 6D, N $$ \mathcal{N} $$ = (1, 1) supersymmetric gauge theories formulated in N $$ \mathcal{N} $$ = (1, 0) harmonic superspace. The off-shell effective action involving all

Abstract We develop an approach to constructing the manifestly Lorentz covariant cubic interaction vertices for the four-dimensional massless higher spin bosonic fields with two-component dotted and undotted spinor indices. Such fields automatically

Abstract We present a new 6D infinite spin field theory in the light-front formulation. The Lorentz-covariant counterparts of these fields depend on 6-vector coordinates and additional spinor variables. Casimir operators in this realization are found

We develop the BRST approach to construct the general off-shell local Lorentz covariant cubic interaction vertices for irreducible massless and massive higher spin fields on d-dimensional Minkowski space. We consider two different cases for interacti

Abstract We study the quantum structure of four-dimensional $${{\mathcal {N}}}=2$$ N = 2 superfield sigma-model formulated in harmonic superspace in terms of the omega-hypermultiplet superfield $$\omega $$ ω . The model is described by harmonic supe

Abstract We introduce a first order description of linearized non-minimal (n = −1) supergravity in superspace, using the unconstrained prepotential superfield instead of the conventionally constrained super one forms. In this description, after int

Abstract We elaborate the generalizations of the approach to gauge-invariant deformations of the gauge theories developed in our previous work (Buchbinder and Lavrov in JHEP 06:097, 2021). In the given paper we construct the exact transformations def

Abstract We consider a general gauge theory with independent generators and study the problem of gauge-invariant deformation of initial gauge-invariant classical action. The problem is formulated in terms of BV-formalism and is reduced to describing

Abstract We develop a novel bi-harmonic N $$ \mathcal{N} $$ = 4 superspace formulation of the N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory (SYM) in four dimensions. In this approach, the N $$ \mathcal{N} $$ = 4 SYM superfield constraints

Abstract We apply the harmonic superspace approach for calculating the divergent part of the one-loop effective action of renormalizable 6D, N $$ \mathcal{N} $$ = (1, 0) supersymmetric higher-derivative gauge theory with a dimensionless coupling cons
