Self-interacting charged massive spin two particles in Minkowski spacetime
Yuichi Ohara
A model of the self-interacting charged massive spin-two field is constructed. We investigate several properties of the model and find that the trivial vacuum is only allowed due t…
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…
