Minimal models of field theories: Chiral higher spin gravity [PDF]
Physical Review D, 2022 There exists a unique class of local Higher Spin Gravities with propagating massless fields in 4 d — Chiral Higher Spin Gravity. Originally, it was formulated in the light-cone gauge.

Toward a twistor action for chiral higher-spin gravity [PDF]
Physical Review D, 2022 A covariant twistor action for chiral higher-spin theory in (A)dS and flat space is constructed in terms of a holomorphic Chern-Simons theory on twistor space. The action reproduces all known cubic vertices of chiral higher-spin theory in flat space. The

Covariant action for conformal higher spin gravity [PDF]
Journal of Physics A: Mathematical and Theoretical, 2022 Conformal higher spin (HS) gravity is a HS extension of Weyl gravity and is a family of local HS theories, which was put forward by Segal and Tseytlin. We propose a manifestly covariant and coordinate-independent action for these theories.

Higher-spin gravity’s “string”: new gauge and proof of holographic duality for the linearized Didenko-Vasiliev solution [PDF]
Journal of High Energy Physics, 2022 We consider type-A higher-spin gravity in AdS4, holographically dual to a free U(N ) vector model on the boundary. We study the linearized version of the Didenko-Vasiliev “BPS black hole”, which we view as this theory’s equivalent of the fundamental ...

Bulk locality and gauge invariance for boundary-bilocal cubic correlators in higher-spin gravity [PDF]
Journal of High Energy Physics, 2022 We consider type-A higher-spin gravity in 4 dimensions, holographically dual to a free O(N) vector model. In this theory, the cubic correlators of higher-spin boundary currents are reproduced in the bulk by the Sleight-Taronna cubic vertex.

New conformal higher spin gravities in 3d [PDF]
Journal of High Energy Physics, 2020 Abstract We propose a new class of conformal higher spin gravities in three dimensions, which extends the one by Pope and Townsend. The main new feature is that there are infinitely many examples of the new theories with a finite number of higher spin fields, much as in the massless case. The action has the Chern-Simons form for a higher spin extension

Exploring the gravity sector of emergent higher-spin gravity: effective action and a solution [PDF]
Journal of High Energy Physics, 2021 We elaborate the description of the semi-classical gravity sector of Yang-Mills matrix models on a covariant quantum FLRW background. The basic geometric structure is a frame, which arises from the Poisson structure on an underlying S2 bundle over space ...

Topologically massive higher spin gravity [PDF]
Journal of High Energy Physics, 2011 We look at the generalisation of topologically massive gravity (TMG) to higher spins, specifically spin-3. We find a special "chiral" point for the spin-three, analogous to the spin-two example, which actually coincides with the usual spin-two chiral point.

Spin-locality of higher-spin theories and star-product functional classes
Journal of High Energy Physics, 2020 The analysis of spin-locality of higher-spin gauge theory is formulated in terms of star-product functional classes appropriate for the β → −∞ limiting shifted homotopy proposed recently in [1] where all ω 2 C 2 higher-spin vertices were shown to be spin-

Journal of High Energy Physics, 2023 Analysis of the first-order corrections to higher-spin equations is extended to homotopy operators involving shift parameters with respect to the spinor Y variables, the argument of the higher-spin connection ω(Y) and the argument of the higher-spin zero-
