Cascading DGP
Claudia de Rham, Gia Dvali, Stefan Hofmann +4
We present a higher codimension generalization of the DGP scenario which, unlike previous attempts, is free of ghost instabilities. The 4D propagator is made regular by embedding o…
Living on a dS brane: Effects of KK modes on inflation
Claudia de Rham, Scott Watson
We develop a formalism to study non-local higher-dimensional effects in braneworld scenarios from a four-dimensional effective theory point of view and check it against the well-kn…
Mimicking Lambda with a spin-two ghost condensate
Claudia de Rham, Andrew J. Tolley
We propose a simple higher-derivative braneworld gravity model which contains a stable accelerating branch, in the absence of cosmological constant or potential, that can be used t…
Gravitational Waves in a Codimension Two Braneworld
Claudia de Rham, Andrew J. Tolley
We consider the propagation of gravitational waves in six dimensions induced by sources living on 3-branes in the context of a recent exact solution hep-th/0506050. The brane geome…
