Covariant constraints of massive gravity in metric formulation
Satoshi Akagi, Taisaku Mori
We propose a simple method for deriving the constraints of the de Rham-Gabadadze-Tolley model in the metric and the Lagrangian formulation, as possible as keeping the Lorentz covar…
Bottom-up approach to massive spin-two theory in arbitrary curved spacetime
Satoshi Akagi
The linear theory of massive spin-two field in arbitrary curved background is investigated. In flat spacetime, the Fierz-Pauli model is well-known as the unique linear theory descr…
Towards construction of ghost-free higher derivative gravity from bigravity
Satoshi Akagi
In this paper, the ghost-freeness of the higher derivative theory proposed by Hassan et al. in [Universe 1 (2015) 2, 92] is investigated. Hassan et al. believed the ghost-freeness…
New massive spin two model on curved space-time
Satoshi Akagi, Yuichi Ohara, Shin'ichi Nojiri
We have proposed a new ghost-free model with interactions of massive spin two particles in Phys.\ Rev.\ D {\bf 90} (2014) 043006 [arXiv:1402.5737 [hep-th]]. Although the model is g…
Stability analysis for new theories of massive spin-two particle and black hole entropy of new bigravity
Yuichi Ohara, Satoshi Akagi, Shin'ichi Nojiri
In Phys.\ Rev.\ D 90 043006 (2014), we proposed a new ghost-free massive spin-two model in flat spacetime. Furthermore, as some extension, we couple the new model with a non-dynami…
Renormalizable toy model of massive spin two field and new bigravity
Yuichi Ohara, Satoshi Akagi, Shin'ichi Nojiri
In this paper, we propose a toy model of the renormalizable theory describing massive spin two field. Although the model is renormalizable, we show that the model contains ghost. T…
