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…
On correlation functions of higher-spin currents in arbitrary dimensions
Melik Karapetyan, Ruben Manvelyan, Karapet Mkrtchyan
We revisit the problem of classification and explicit construction of the conformal three-point correlation functions of currents of arbitrary integer spin in arbitrary dimensions.…
Interactions of massless fermionic fields in three dimensions
Stefan Fredenhagen, Filipp Lausch, Karapet Mkrtchyan
All independent interaction vertices involving massless (Fang--Fronsdal) fermions in three dimensions are classified, completing the classification of interactions of massless fiel…
