Brane Cosmology in an Arbitrary Number of Dimensions
N. Chatillon, C. Macesanu, M. Trodden
We derive the effective cosmological equations for a non- symmetric codimension one brane embedded in an arbitrary D-dimensional bulk spacetime, generalizing the $D=5…
Cosmic Acceleration and Modified Gravity
Mark Trodden
I briefly discuss some attempts to construct a consistent modification to General Relativity (GR) that might explain the observed late-time acceleration of the universe and provide…
The Cosmology - Particle Physics Connection
Mark Trodden
Modern cosmology poses deep and unavoidable questions for fundamental physics. In this plenary talk, delivered in slightly different forms at the {\it Particles and Nuclei Internat…
Ghosts, Instabilities, and Superluminal Propagation in Modified Gravity Models
Antonio De Felice, Mark Hindmarsh, Mark Trodden
We consider Modified Gravity models involving inverse powers of fourth-order curvature invariants. Using these models' equivalence to the theory of a scalar field coupled to a line…
On Dark Matter Self-Interactions from Higher Dimensional Gravity
Nicolas Chatillon, Cosmin Macesanu, Aleksandr Pinzul +1
It has recently been suggested that in a brane world scenario with large extra dimensions, short distance gravitational interactions can enhance the dark matter scattering cross-se…
