Free massless higher-superspin superfields on the anti-de Sitter superspace

S. M. Kuzenko, A. G. Sibiryakov

Free massless higher-superspin superfields on the N=1, D=4 anti-de Sitter superspace are introduced. The linearized gauge transformations are postulated. Two families of dually equ…

Lagrange Anchor and Characteristic Symmetries of Free Massless Fields

Dmitry S. Kaparulin, Simon L. Lyakhovich, Alexey A. Sharapov

A Poincaré covariant Lagrange anchor is found for the non-Lagrangian relativistic wave equations of Bargmann and Wigner describing free massless fields of spin in four-dime…

Local BRST cohomology in (non-)Lagrangian field theory

D. S. Kaparulin, S. L. Lyakhovich, A. A. Sharapov

Some general theorems are established on the local BRST cohomology for not necessarily Lagrangian gauge theories. Particular attention is given to the BRST groups with direct physi…

Remarks on l-conformal extension of the Newton-Hooke algebra

Anton Galajinsky, Ivan Masterov

The l-conformal extension of the Newton-Hooke algebra proposed in [J. Math. Phys. 38 (1997) 3810] is formulated in the basis in which the flat space limit is unambiguous. Admissibl…

On manifolds admitting the consistent Lagrangian formulation for higher spin fields

I. L. Buchbinder, V. A. Krykhtin, P. M. Lavrov

We study a possibility of Lagrangian formulation for free higher spin bosonic totally symmetric tensor field on the background manifold characterizing by the arbitrary metric, vect…
