Toward a twistor action for chiral higher-spin gravity
Published 2 Sep 2022 in hep-th | (2209.00925v2)
Abstract: 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 spacetime action of the holomorphic Chern-Simons theory in flat space is also obtained.
