A general mass term for bigravity
Giulia Cusin, Ruth Durrer, Pietro Guarato +1
We introduce a new formalism to study perturbations of Hassan-Rosen bigravity theory, around general backgrounds for the two dynamical metrics. In particular, we derive the general…

Inflationary perturbations in bimetric gravity
Giulia Cusin, Ruth Durrer, Pietro Guarato +1
In this paper we study the generation of primordial perturbations in a cosmological setting of bigravity during inflation. We consider a model of bigravity which can reproduce the…
