After a decade and a half of research motivated by the accelerating universe, theory and
experiment have reached a certain level of maturity. The development of theoretical models …

We review recent progress in massive gravity. We start by showing how different theories of
massive gravity emerge from a higher-dimensional theory of general relativity, leading to the …

Recently, aLIGO announced the first direct detections of gravitational waves, a direct
manifestation of the propagating degrees of freedom of gravity. The detected signals …

We show that it is impossible to improve the high-energy behavior of the tree-level four-point
amplitude of a massive spin-2 particle by including the exchange of any number of scalars …

A bstract We consider various decoupling limits of ghost-free massive gravity on (A) dS. The
first is a decoupling limit on AdS space where the mass goes to zero while the AdS radius is …

In this paper we investigate the case of nonminimal coupling in the (extended) nonlinear
massive gravity theories. We first consider massive gravity in the Brans-Dicke background …

The theory of nonlinear massive gravity can be extended into the F (R) form as developed by
Cai et al.[Phys. Rev. D 90, 064051 (2014)]. Being free of the Boulware-Deser ghost, such a …

The unique ghost-free mass and nonlinear potential terms for general relativity are
presented in a diffeomorphism and local Lorentz invariant vierbein formalism. This …

Cubic Galileon massive gravity is a development of de Rham–Gabadadze-Tolley massive
gravity theory in which the space of the Stueckelberg field is broken. We consider the cubic …

We propose a nonlinear massive gravitational theory which includes F (R) modifications.
This construction inherits the benefits of the de Rham-Gabadadze-Tolley model and is free …
