GAUGE-INVARIANT LAGRANGIANS FOR FREE AND INTERACTING HIGHER SPIN FIELDS:
A REVIEW OF THE BRST FORMULATION | International Journal of Modern Physics A World …

This review is devoted to the intriguing and still largely unexplored links between string
theory and higher spins, the types of excitations that lie behind their most cherished …

A bstract We develop massive higher-spin theory as a framework for describing dynamics of
rotating compact objects, such as Kerr black holes. In this paper, we explore gauge …

The explicit covariant actions and propagators are given for fields describing particles of all
spins and masses, in any spacetime dimension. Massive particles are realized as …

String Theory includes a plethora of higher-spin excitations, which clearly lie behind its most
spectacular properties, but whose detailed behavior is largely unknown. Conversely, string …

A bstract Scattering of two Kerr Black Holes emitting gravitational waves can be captured by
an effective theory of a massive higher-spin field interacting with the gravitational field. While …

We construct an off-shell extension of cubic interaction vertices between massless bosonic
Higher Spin fields on a flat background which can be obtained from perturbative bosonic …

Using Noether's procedure we present a complete solution for the trilinear interactions of
arbitrary spins s1, s2, s3 in a flat background, and discuss the possibility to enlarge this …

Cubic interactions of higher-spin gauge fields in (A) dSd are studied in the metric-like
approach. Making use of the traceless and transverse constraints together with the ambient …

For free-field theories associated with BRST first-quantized gauge systems, we identify
generalized auxiliary fields and pure gauge variables already at the first-quantized level as …
