Minimal model of Chiral Higher Spin Gravity
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]
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.

Actions for self-dual Higher Spin Gravities [PDF]
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.

Quantum Chiral Higher Spin Gravity [PDF]
An example of a higher spin gravity in four-dimensional flat space has recently been constructed in arXiv:1609.04655 [hep-th]. This theory is chiral and the action is written in the light-cone gauge. The theory has certain stringy features, e.g. admits Chan-Paton factors.

Supersymmetric quantum chiral higher spin gravity
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).

Characteristic cohomology and observables in higher spin gravity [PDF]
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 ...

Type-B formal higher spin gravity [PDF]
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.

How higher-spin gravity surpasses the spin-two barrier [PDF]
Aiming at nonexperts, the key mechanisms of higher-spin extensions of ordinary gravities in four dimensions and higher are explained. An overview of various no-go theorems for low-energy scattering of massless particles in flat spacetime is given. In doing so, a connection between the $S$-matrix and the Lagrangian approaches is made, exhibiting their ...

Chaos in three-dimensional higher spin gravity [PDF]
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

Low spin solutions of higher spin gravity: BPST instanton
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.
