We analyze the physics of massive spin-2 fields in (A)dS backgrounds and exhibit that: The theory is stable only for masses m2⩾2Λ/3, where the conserved energy associated with the background timelike Killing vector is positive, while the instability for m^2<2Λ/3 is traceable to the helicity 0 energy. The stable, unitary, partially massless theory at m^2=2Λ/3 describes 4 propagating degrees of freedom, corresponding to helicities (±2,±1) but contains no 0 helicity excitation.

Massive Gravity (2014, background): “This special case is another point in parameter space where the helicity-0 mode could be decoupled, corresponding to a partially massless (PM) theory of gravity as first pointed out by Deser and Waldron [190, 189, 188], (see also [500] for partially massless higher spin, and [450] for related studie”
Cosmological stability bound in massive gravity and bigravity (2013, background): “elicity-0 mode becomes a ghost. This result follows because these solutions begin to violate a generalization of a cosmological bound on the mass of graviton ﬁrst discovered by Higuchi [59] (see also [60, 61]) This generalization of the Higuchi bound to FRW massive gravity was derived in [55] and in”
