On Lagrangian formulations for arbitrary bosonic HS fields on Minkowski backgrounds
We review the details of unconstrained Lagrangian formulations for Bose
particles propagated on an arbitrary dimensional flat space-time and described
by the unitary irreducible integer higher-spin representations of the Poincare
group subject to Young tableaux with rows. The procedure
is based on the construction of Verma modules and finding auxiliary oscillator
realizations for the symplectic algebra which encodes the second-class
operator constraints subsystem in the HS symmetry algebra. Application of an
universal BRST approach reproduces gauge-invariant Lagrangians with reducible
gauge symmetries describing the free dynamics of both massless and massive
bosonic fields of any spin with appropriate number of auxiliary fields.Comment: 8 pages, no figures, extended Contribution to the Proceedings of the
