Continuous spin superparticle model
I. L. Buchbinder, S. A. Fedoruk
We construct a new model of a particle propagating in , superspace that describes the dynamics of a continuous spin irreducible representation of the Poincaré supe…
Continuous spin superparticle in , curved superspace
I. L. Buchbinder, S. A. Fedoruk
We present a new particle model that describes the dynamics of a continuous spin particle in superspace and is a generalization of the continuous-…
On BRST Lagrangian formulation for massive higher-spin fields in Minkowski space
I. L. Buchbinder, S. A. Fedoruk, V. A. Krykhtin
We give a brief overview of the BRST approach to the gauge invariant Lagrangian formulation for free massive higher-spin bosonic fields focusing on two specific aspects. First, the…
On BRST Lagrangian formulation of massless higher spin fields
I. L. Buchbinder, S. A. Fedoruk, A. P. Isaev +1
The paper is dedicated to the blessed memory of Professor Vladislav Gavrilovich Bagrov, an outstanding Russian scientist in the area of theoretical and mathematical physics. He had…
On the realization of infinite (continuous) spin field representations in AdS space
I. L. Buchbinder, S. A. Fedoruk, A. P. Isaev +1
We study the symmetry properties of infinite spin fields in space which are involved in the Lagrangian model proposed in arXiv:2403.14446 where the main role is played…
BRST construction for infinite spin field on
I. L. Buchbinder, S. A. Fedoruk, A. P. Isaev +1
We generalize the first class constraints that describe the infinite spin irreducible Poincaré group representation in flat space to new first class constraints in spa…
Infinite (continuous) spin particle in constant curvature space
I. L. Buchbinder, S. A. Fedoruk, A. P. Isaev +1
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 coo…
Generalization of the Bargmann-Wigner approach to constructing relativistic fields
I. L. Buchbinder, S. A. Fedoruk, A. P. Isaev +1
We review the method for constructing local relativistic fields corresponding to the Bargmann-Wigner wave functions that describe the unitary irreducible representations of the $4D…
