Higher-derivative gravity in brane world models
M. Parry, S. Pichler, D. Deeg
We investigate brane world models in higher-derivative gravity theories where the gravitational Lagrangian is an arbitrary function of the Ricci scalar. Making use of the conformal…

New bulk scalar field solutions in brane worlds
M. Parry, S. Pichler
We use nonlinear perturbation theory to obtain new solutions for brane world models that incorporate a massive bulk scalar field. We then consider tensor perturbations and show tha…
