摘要：
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.
