String model for AdS gravity and higher spins [PDF]

Physical Review D, 2011
We construct a string sigma-model which low energy limit describes the anti de Sitter gravity and spin 3 massless fields in Vasiliev's frame-like formalism. The model is based on vertex operators generating vielbein and connection fields in the Mac Dowell - Mansoury - Stelle - West (MMSW) formulation of gravity. The structure of the vertex operators is

Conformal higher spin scattering amplitudes from twistor space

Journal of High Energy Physics, 2017
We use the formulation of conformal higher spin (CHS) theories in twistor space to study their tree-level scattering amplitudes, finding expressions for all three-point M H V ¯ $$ \overline{\mathrm{MHV}} $$ amplitudes and all MHV amplitudes involving ...

Higher-spin self-dual General Relativity: 6d and 4d pictures, covariant vs. lightcone

Journal of High Energy Physics
We study the higher-spin extension of self-dual General Relativity (GR) with cosmological constant, proposed by Krasnov, Skvortsov and Tran. We show that this theory is actually a gauge-fixing of a 6d diffeomorphism-invariant Abelian theory, living on ...

On massive higher spins and gravity. Part II. Spin 3

Journal of High Energy Physics
In this paper, we continue our investigation of gravitational interactions for massive higher spins, extending our recent work on massive spin 5/2 to massive spin 3, including its massless and partially massless limits.

Higher-spin extended conformal algebras and -gravities

Nuclear Physics B, 1991
Abstract The construction of classical 3 gravity is reviewed. It is suggested that the hidden symmetry for quantum 3 gravity in the chiral gauge is not SL(3, R ) but a group contraction of this. ISL(2, R ). This is extended to N gravity, and the case of 4 gravity is presented in detail.

On massive higher spins and gravity. Part III. Spin 7/2

Journal of High Energy Physics
In this paper, we extend our previous results on the gravitational interactions for massive spin 5/2 particles and spin 3 particles to massive spin 7/2, including its massless and partially massless limits.
