Existence of ghost-eliminating constraints in multivielbein theory
J. Flinckman, S. F. Hassan
We perform a Hamiltonian constraint analysis of the multivielbein theory proposed in [Phys. Rev. Lett. 122 (2019) 251101]. The analysis shows that the secondary constraints have th…

Mass spectrum and linear perturbations of ghost-free multi-spin-2 theory
J. Flinckman, S. F. Hassan
Motivated by the spin-2 nature of gravity, we consider a theory of N interacting spin-2 fields, formulated in terms of vielbeins which have been argued to be free of the Boulware-D…
