Resummation of Massive Gravity
Claudia de Rham, Gregory Gabadadze, Andrew J. Tolley
We construct four-dimensional covariant non-linear theories of massive gravity which are ghost-free in the decoupling limit to all orders. These theories resum explicitly all the n…
Galileon inflation
Clare Burrage, Claudia de Rham, David Seery +1
Galileon inflation is a radiatively stable higher derivative model of inflation. The model is determined by a finite number of relevant operators which are protected by a covariant…
DBI and the Galileon reunited
Claudia de Rham, Andrew J. Tolley
We derive the relativistic generalization of the Galileon, by studying the brane position modulus of a relativistic probe brane embedded in a five- dimensional bulk. In the appropr…
Cascading Gravity is Ghost Free
Claudia de Rham, Justin Khoury, Andrew J. Tolley
We perform a full perturbative stability analysis of the 6D cascading gravity model in the presence of 3-brane tension. We demonstrate that for sufficiently large tension on the (f…
