Minimal model of Chiral Higher Spin Gravity [PDF]

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

Supersymmetric quantum chiral higher spin gravity [PDF]

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).

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 ...

Low spin solutions of higher spin gravity: BPST instanton [PDF]

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.

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.

Chern-Simons Matter Theories and Higher Spin Gravity [PDF]

Journal of High Energy Physics, 2017
We compute the parity violating three point amplitudes with one scalar leg in higher spin gravity and compare results with those of Chern-Simons matter theories. The three-point correlators of the free boson, free fermion, critical vector model and Gross-

Strong homotopy algebras for chiral higher spin gravity via Stokes theorem [PDF]

Journal of High Energy Physics, 2023
Chiral higher spin gravity is defined in terms of a strong homotopy algebra of pre-Calabi-Yau type (noncommutative Poisson structure). All structure maps are given by the integrals over the configuration space of concave polygons and the first two maps ...

Metaplectic representation and ordering (in)dependence in Vasiliev’s higher spin gravity [PDF]

Journal of High Energy Physics, 2022
We investigate the formulation of Vasiliev’s four-dimensional higher-spin gravity in operator form, without making reference to one specific ordering.

Higher Spin Matrix Models

Universe, 2017
We propose a hybrid class of theories for higher spin gravity and matrix models, i.e., which handle simultaneously higher spin gravity fields and matrix models.

Quantizing higher-spin gravity in free-field variables [PDF]

Journal of High Energy Physics, 2018
We study the formulation of massless higher-spin gravity on AdS$_3$ in a gauge in which the fundamental variables satisfy free field Poisson brackets.
