Biaxially symmetric solutions to 4D higher spin gravity [PDF]
Journal of Physics A: Mathematical and Theoretical, 2013 We review some aspects of biaxially symmetric solutions to Vasiliev's equations in four dimensional spacetime with negative cosmological constant. The solutions, which activate bosonic fields of all spins, are constructed using gauge functions, projectors and deformed oscillators.

Conformal higher-spin gravity: linearized spectrum = symmetry algebra [PDF]
Journal of High Energy Physics, 2018 Abstract The linearized spectrum and the algebra of global symmetries of conformal higher-spin gravity decompose into infinitely many representations of the conformal algebra. Their characters involve divergent sums over spins. We propose a suitable regularization adapted to their evaluation and observe that their characters are ...

Higher-spin self-dual Yang-Mills and gravity from the twistor space
Journal of High Energy Physics, 2023 We lift the recently proposed theories of higher-spin self-dual Yang-Mills (SDYM) and gravity (SDGR) to the twistor space. We find that the most natural room for their twistor formulation is not in the projective, but in the full twistor space, which is ...

Planar solutions of higher-spin theory. Part I. Free field level
Journal of High Energy Physics, 2021 Many black hole solutions of General Relativity are known to be linearly exact. This opens a way to study them in gauge theories that apart from gravity contain fields of higher spin s > 2.

More on Chiral Higher Spin Gravity and convex geometry
Nuclear Physics B, 2023 Recently, a unique class of local Higher Spin Gravities with propagating massless fields in $4d$ - Chiral Higher Spin Gravity - was given a covariant formulation both in flat and $(A)dS_4$ spacetimes at the level of equations of motion. We unfold the corresponding homological perturbation theory as to explicitly obtain all interaction vertices.

Strong homotopy algebras for chiral higher spin gravity via Stokes theorem
Journal of High Energy PhysicsChiral 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 ...

Partially-massless higher spin algebras in four dimensions
Journal of High Energy PhysicsWe propose a realisation of partially-massless higher spin algebras in four dimensions in terms of bosonic and fermionic oscillators, using Howe duality between sp(4, ℝ) ≅ so(2, 3) and osp(1|2(ℓ − 1), ℝ).

Linearized Coxeter higher-spin theories
Journal of High Energy PhysicsA class of higher-spin gauge theories on AdS 4 associated with various Coxeter groups C $$ \mathcal{C} $$ is analyzed at the linear order. For a general C $$ \mathcal{C} $$ , a solution corresponding to the AdS 4 space and the form of the free unfolded ...

Scattering amplitudes for all masses and spins
Journal of High Energy Physics, 2021 We introduce a formalism for describing four-dimensional scattering amplitudes for particles of any mass and spin. This naturally extends the familiar spinor-helicity formalism for massless particles to one where these variables carry an extra SU(2 ...
