Matter-free higher spin gravities in 3D: Partially-massless fields and general structure

M Grigoriev, K Mkrtchyan, E Skvortsov - Physical Review D, 2020 - APS
We study the problem of interacting theories with partially-massless and conformal higher
spin fields without matter in three dimensions. A new class of theories that have partially …

New conformal higher spin gravities in 3d

Higher spin analogs of linearized topologically massive gravity and linearized new massive gravity

D Dalmazi, ALR Dos Santos - Physical Review D, 2021 - APS
We suggest a new spin-4 self-dual model (parity singlet) and a new spin-4 parity doublet in
D= 2+ 1. They are of higher order in derivatives and are described by a totally symmetric …
