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

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 [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.

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.

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-

Shifted homotopy analysis of the linearized higher-spin equations in arbitrary higher-spin background

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-

On BF-type higher-spin actions in two dimensions

Journal of High Energy Physics, 2020
We propose a non-abelian higher-spin theory in two dimensions for an infinite multiplet of massive scalar fields and infinitely many topological higher-spin gauge fields together with their dilaton-like partners.

Spin-locality of η 2 and η ¯ 2 $$ {\overline{\eta}}^2 $$ quartic higher-spin vertices

Journal of High Energy Physics, 2020
Higher-spin theory contains a complex coupling parameter η. Different higher-spin vertices are associated with different powers of η and its complex conjugate η ¯ $$ \overline{\eta} $$ .

On holomorphic sector of higher-spin theory

Journal of High Energy Physics, 2022
Recent investigation of the locality problem for higher-spin fields led to a vertex reconstruction procedure that involved elements of contraction of the original Vasiliev interaction algebra.

Chiral approach to partially-massless fields

Journal of High Energy Physics, 2023
We propose a new (chiral) description of partially-massless fields in 4d, including the partially-massless graviton, that is similar to the pure connection formulation for gravity and massless higher spin fields, the latter having a clear twistor origin.
