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…
Linearised gravity as edge modes & manifest duality and Lorentz covariance
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…
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…
Spinor-helicity representations of (A)dS particles of any mass
Thomas Basile, Euihun Joung, Karapet Mkrtchyan +1
The spinor-helicity representations of massive and (partially-)massless particles in four dimensional (Anti-) de Sitter spacetime are studied within the framework of the dual pair…
Democracy from topology
Oleg Evnin, Euihun Joung, Karapet Mkrtchyan
Chiral form fields in dimensions can be effectively described as edge modes of topological Chern-Simons theories in dimensions. At the same time, manifestly Lorentz-invar…
