Higher-Spin dS/CFT beyond minimal type-A, and the doubled nature of de Sitter space
Julian Lang, Yasha Neiman
We study the holographic duality between free vector models and Higher-Spin Gravity in 4-dimensional de Sitter space. On both the bulk and boundary sides, we introduce new reality…
Universal structure in the interactions of massless fields on the lightcone
Jin Kozaki, Yasha Neiman
We consider cubic interactions of massless fields of arbitrary spin in 4 spacetime dimensions, within the lightcone formalism. We extend two key results from flat to (Anti-)de Sitt…
Causality of higher-spin interactions on the (A)dS lightcone, with application to the static patch
Jin Kozaki, Julian Lang, Yasha Neiman
We study Higher-Spin Gravity in 4-dimensional (Anti-)de Sitter space, at leading order in the interactions (cubic vertices), in the AdS lightcone formalism developed by Metsaev. Us…
Higher-spin self-dual General Relativity: 6d and 4d pictures, covariant vs. lightcone
Yasha Neiman
We study the higher-spin extension of self-dual General Relativity (GR) with cosmological constant, proposed by Krasnov, Skvortsov and Tran. We show that this theory is actually a…
N=2 supersymmetry in the twistor description of higher-spin holography
Julian Lang, Yasha Neiman
We study the holographic duality between higher-spin (HS) gravity in 4d and free vector models in 3d, with special attention to the role of N=2 supersymmetry (SUSY). For the type-A…
Quartic locality of higher-spin gravity in de Sitter and Euclidean anti-de Sitter space
Yasha Neiman
We consider higher-spin gravity in (A)dS_4, defined as the holographic dual of a free O(N) or Sp(N) vector model. At the quartic level, this theory has been judged non-local at dis…
