Superluminal Propagation and Acausality of Nonlinear Massive Gravity
S. Deser, K. Izumi, Y. C. Ong +1
Massive gravity is an old idea: trading geometry for mass. Much effort has been expended on establishing a healthy model, culminating in the current ghost-free version. We summariz…
Non-Einstein source effects in massive gravity
S. Deser, A. Waldron
We exhibit novel effects (absent in GR) of sources in massive gravity. First, we show that removing its ghost mode forces a field-current identity: The metric's trace is locally pr…
Massive Gravity Acausality Redux
S. Deser, K. Izumi, Y. C. Ong +1
Massive gravity (mGR) is a 5(=2s+1) degree of freedom, finite range extension of GR. However, amongst other problems, it is plagued by superluminal propagation, first uncovered via…
No consistent bimetric gravity?
S. Deser, M. Sandora, A. Waldron
We discuss the prospects for a consistent, nonlinear, partially massless (PM), gauge symmetry of bimetric gravity (BMG). Just as for single metric massive gravity, we show that con…
Nonlinear Partially Massless from Massive Gravity?
S. Deser, M. Sandora, A. Waldron
We show that consistent nonlinear Partially Massless models cannot be obtained starting from "f-g" massive gravity, with "f" the embedding de Sitter space. The obstruction, which i…
PM = EM: Partially Massless Duality Invariance
S. Deser, A. Waldron
In d=4 de Sitter space, novel conformally invariant photon-like theories consistently couple to charged matter. We show that these higher spin, maximal depth, partially massless sy…
