Minimal model of Chiral Higher Spin Gravity

Journal of High Energy Physics, 2022
A unique class of local Higher Spin Gravities with propagating massless fields in 4d — Chiral Higher Spin Gravity — was first found in the light-cone gauge. We construct a covariant form of the corresponding field equations in all orders, thus completing

One-loop finiteness of Chiral Higher Spin Gravity [PDF]

Journal of High Energy Physics, 2020
One of the main ideas behind Higher Spin Gravities is that the higher spin symmetry is expected to leave no room for counterterms, thereby eliminating UV divergences that make the pure gravity non-renormalizable.

Low spin solutions of higher spin gravity: BPST instanton

Journal of High Energy Physics
Higher spin gravities do not have a low energy limit where higher-spin fields decouple from gravity. Nevertheless, it is possible to construct fine-tuned exact solutions that activate low-spin fields without sourcing the higher-spin fields.

Actions for self-dual Higher Spin Gravities [PDF]

Journal of High Energy Physics, 2021
Higher Spin Gravities are scarce, but covariant actions for them are even scarcer. We construct covariant actions for contractions of Chiral Higher Spin Gravity that represent higher spin extensions of self-dual Yang-Mills and self-dual Gravity theories.

Characteristic cohomology and observables in higher spin gravity [PDF]

Journal of High Energy Physics, 2020
We give a complete classification of dynamical invariants in 3d and 4d Higher Spin Gravity models, with some comments on arbitrary d. These include holographic correlation functions, interaction vertices, on-shell actions, conserved currents, surface ...

Supersymmetric quantum chiral higher spin gravity

Journal of High Energy Physics, 2022
We study quantum properties of supersymmetric N $$ \mathcal{N} $$ = 1 and N $$ \mathcal{N} $$ = 4 extensions of the four dimensional bosonic Chiral Higher Spin Gravities (HiSGRAs).

Type-B formal higher spin gravity [PDF]

Journal of High Energy Physics, 2018
We propose non-linear equations for the formal Type-B Higher Spin Gravity that is dual to the free fermion or to the Gross-Neveu model, depending on the boundary conditions.

Chaos in three-dimensional higher spin gravity [PDF]

Journal of High Energy Physics, 2019
We discuss SL(N, ℂ) Chern-Simons higher spin gauge theories in Euclidean AdS3. With appropriate boundary term, we derive the higher spin generalization of Schwarzian on-shell action. We investigate gravitationally dressed bi-locals, and we study the soft

Boundary freedom in higher spin gravity

Physics Letters B
We investigate new boundary conditions in three-dimensional asymptotically Anti–de Sitter gravity coupled to higher-spin fields, allowing for arbitrary boundary degrees of freedom.

On the spectrum of pure higher spin gravity [PDF]

Journal of High Energy Physics, 2020
Abstract We study the spectrum of pure massless higher spin theories in AdS3. The light spectrum is given by a tower of massless particles of spin s = 2, ⋯ , N and their multi-particles states. Their contribution to the torus partition function organises into the vacuum character of the $$ {\mathcal{W}}_N $$
