| Description | We perform the Hamiltonian analysis of the bimetric theory of gravity introduced in S. F. Hassan and R. A. Rosen, J. High Energy Phys.1202, 126 (2012), arXiv:1109.3515 [hep-th]. We carefully analyze the requirement of the preservation of all constraints and we find that there is no additional constraint that could eliminate the ghost mode. |
