New higher-spin topological systems in 3D

Seminar

Seminar talk

Nicolas Boulanger (UMONS)

Motivated by the generation of action principles from off-shell dualisation, we present a general class of free, topological theories in three dimensions that exhibit higher-spin gauge invariance.

In the spin-2 case, we recover the triplet system already known before. The higher-spin systems that we obtain, on the other hand, seem to be new.

We show that the flat limit of our action around (A)dS_3 background gives rise to a one-parameter family of inequivalent actions in Minkowski space, whose non-Abelian deformations are studied.
