Canonical structure of massive (bi-) gravity
PARTICLES AND ACCELERATORS
We consider the Hamiltonian structure of massive (bi)-gravity in HR (Hassan and Rosen) variables. We give necessary conditions for the interaction term of such a theory to be ghost free. We show that in the bi-gravity of HR, there exist enough additional constraints for omitting the ghost and generating diffeomorphism, as well.
