Abstract:

Gravitational Higgs mechanism provides a non-perturbative definition of massive gravity. While perturbatively unitarity is not evident, a non-perturbative Hamiltonian appears to suggest that no negative norm state is present in the full nonlinear theory. Instead, there are additional non-perturbative time-dependent vacuum solutions, both when the basic massive gravity background is Minkowski and de Sitter.
