Journal ArticleDOI
Degenerate higher order scalar-tensor theories beyond Horndeski up to cubic order
Jibril Ben Achour,Marco Crisostomi,Kazuya Koyama,David Langlois,Karim Noui,Karim Noui,Gianmassimo Tasinato +6 more
TL;DR: In this paper, all scalar-tensor Lagrangians that are cubic in second derivatives of a scalar field, and that are degenerate, hence avoiding Ostrogradsky instabilities, were presented.
Journal ArticleDOI
Extended scalar-tensor theories of gravity
TL;DR: In this article, the authors study new consistent scalar-tensor theories of gravity with potentially interesting cosmological applications and derive the conditions for the existence of a primary constraint that prevents the propagation of an additional dangerous mode associated with higher order equations of motion.
Journal ArticleDOI

TL;DR: In this article, a simple parametrization of the effect in terms of two parameters (Ξ 0,n) was proposed to test modified GW propagation with standard sirens with LISA.
Journal ArticleDOI
FRW Cosmology in Ghost Free Massive Gravity
Journal ArticleDOI
Perturbations in Massive Gravity Cosmology
TL;DR: In this article, the authors studied cosmological perturbations for a ghost free massive gravity theory formulated with a dynamical extra metric that is needed to massive deform GR, and showed that the perturbation is strongly coupled in the first branch, while in the second branch the expected degrees of freedom propagate.
