Journal ArticleDOI
How higher-spin gravity surpasses the spin-two barrier
TL;DR: In this paper, the key mechanisms of higher-spin extensions of ordinary gravities in four dimensions and higher are explained, and an overview of various no-go theorems for low-energy scattering of massless particles in flat spacetime is given.
Journal ArticleDOI
Inconsistency of interacting, multi-graviton theories
TL;DR: In this article, it was shown that there is no consistent (ghost-free) coupling, with at most two derivatives of the fields, that can mix the various "gravitons".
Journal ArticleDOI
Tensor Gauge Fields in Arbitrary Representations of GL(D, ℝ). Duality and Poincaré Lemma
Xavier Bekaert,Nicolas Boulanger +1 more
TL;DR: In this paper, a generalization of the Poincare lemma for free gauge fields has been shown to generalize the de Rham complex for p-form gauge fields.
Journal ArticleDOI
On The Uniqueness of Minimal Coupling in Higher-Spin Gauge Theory
TL;DR: In this paper, the uniqueness of the minimal couplings between higher-spin fields and gravity has been studied in the context of higher spin field equations with ε > 0 and ε = 3.
Journal ArticleDOI
On geometric equations and duality for free higher spins
Xavier Bekaert,Nicolas Boulanger +1 more
TL;DR: In this article, a general scheme for dualising higher-spin gauge fields in arbitrary irreducible representations of GL(D, R ) was proposed, and a recipe for constructing Fronsdal-like field equations and Lagrangians for such exotic fields was given.
