Description
In this paper, we discuss massive gravity in Minkowski space via the gravitational Higgs mechanism, which provides a nonperturbative definition thereof. Using this nonperturbative definition, we address the issue of unitarity by studying the full nonlinear Hamiltonian for the relevant metric degrees of freedom. While perturbatively unitarity is not evident, we argue that no negative norm state is present in the full nonlinear theory.
