The only consistent linear theory for a massive spin-2 field on a flat space-time has been known for a long time as being the Fierz-Pauli theory. Its promotion to a non-linear theory, although essential, has long been thought impossible because of the appearance of the Boulware-Deser (BD) ghost. Recently de Rham Gabadadze and Tolley proposed a family of massive gravity theories, free of this ghost. We will present, for a particular subset of these theories, how to obtain the linearised field… CONTINUE READING
