We revisit the problem of building consistent interactions for a multiplet of partially massless spin-2 fields in (anti-)de Sitter space. After rederiving and strengthening the existing no-go result on the impossibility of Yang-Mills type non-abelian deformations of the partially massless gauge algebra, we prove the uniqueness of the cubic interaction vertex and field-dependent gauge transformation that generalize the structures known from single-field analyses. Unlike in the case of one… Expand
Interactions for Partially-Massless Spin-2 Fields
Partially massless (PM) fields of spin-2 have been subject to renewed attention in recent years after the important advances made in the understanding of massive gravity [1,2]. In four-dimensional deExpand

Looking for partially-massless gravity
We study the possibility for a unitary theory of partially-massless (PM) spin-two field interacting with Gravity in arbitrary dimensions. We show that the gauge and parity invariant interaction of PMExpand
No-go theorems for unitary and interacting partially massless spin-two fields.
TLDR
There cannot exist a unitary theory of a PM spin-two field coupled to Einstein gravity with a perturbatively local Lagrangian, and it is shown that the PM limit of massive gravity also lacks the PM gauge symmetry. Expand
Non-linear partially massless symmetry in an SO(1,5) continuation of conformal gravity
We construct a non-linear theory of interacting spin-2 fields that is invariant under the partially massless (PM) symmetry to all orders. This theory is based on the SO(1, 5) group, in analogy withExpand
No-go for partially massless spin-2 Yang-Mills
