Metric-like Cubic Vertices for Massless Bosonic Higher-Spin Fields in AdS
Freddie King, Taylor Pomfret, Karapet Mkrtchyan
We derive parity-even transverse-traceless metric-like cubic vertices for massless bosonic higher-spin fields in AdS. Starting from the known two- and three-derivative vertices…

Manifest duality and Lorentz covariance for linearised gravity as edge modes
Calvin Y. -R. Chen, Euihun Joung, Karapet Mkrtchyan
We present the first formulation of linearised gravity in four dimensions which is manifestly Lorentz covariant and democratic, i.e. treats the two frames related by electric-magne…

Higher-order chiral scalar from boundary reduction of 3d higher-spin gravity
Calvin Yi-Ren Chen, Euihun Joung, Karapet Mkrtchyan +1
We use a recently proposed covariant procedure to reduce the Chern-Simons action of three-dimensional higher-spin gravity to the boundary, resulting in a Lorentz covariant action f…
