Covariant Cubic Interacting Vertices for Massless and Massive Integer Higher Spin Fields

We develop the BRST approach to construct the general off-shell local Lorentz covariant cubic interaction vertices for irreducible massive higher spin fields on $d$-dimensional Minkowski space. We

Chiral Approach to Massive Higher Spins.

We propose a new, chiral description for massive higher-spin particles in four spacetime dimensions, which facilitates the introduction of consistent interactions. As proof of concept, we formulate

Unfolded Fierz-Pauli equations in three-dimensional asymptotically flat spacetimes

We utilise a quotient of the universal enveloping algebra of the Poincaré algebra in three spacetime dimensions, on which we formulate a covariant constancy condition. The equations so obtained

BRST-BV approach for interacting higher spin fields

We develop the BRST-BV approach to construct the general off-shell Lorentz covariant cubic, quartic, $e$-tic interaction vertices for irreducible higher spin fields on $d$-dimensional Minkowski

There are various no-go theorems that tightly constrain the existence of local higher-spin theories with non-trivial S -matrix in flat space. Due to the existence of higher-spin Yang-Mills theory

Using light-cone gauge formulation, massive arbitrary spin irreducible fields and massless (scalar and spin one-half) fields in three-dimensional flat space are considered. Both the integer spin and

Interacting higher-spin gauge fields on the light front

In the light-front formulation of particle dynamics the authors introduce transverse creation and annihilation operators. Using these they formulate a free-field theory containing all massless
