Massive graviton as a testable cold dark matter candidate
We construct a model of gravity where the tensor graviton mode is massive, while spatially flat cosmological solutions and linearized equations for scalar and vector metric perturbations are not modified. This model is free of the vDVZ discontinuity and strong coupling problem, has no ghosts and doe...
