Higher-spin symmetry vs. boundary locality, and a rehabilitation of dS/CFT
Adrian David, Yasha Neiman
We consider the holographic duality between 4d type-A higher-spin gravity and a 3d free vector model. It is known that the Feynman diagrams for boundary correlators can be encapsul…

Spinor-helicity variables for cosmological horizons in de Sitter space
Adrian David, Nico Fischer, Yasha Neiman
We consider massless fields of arbitrary spin in de Sitter space. We introduce a spinor-helicity formalism, which encodes the field data on a cosmological horizon. These variables…
