Scaling Solutions to 6D Gauged Chiral Supergravity
A. J. Tolley, C. P. Burgess, C. de Rham +1
We construct explicitly time-dependent exact solutions to the field equations of 6D gauged chiral supergravity, compactified to 4D in the presence of up to two 3-branes situated wi…
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…
High-energy effective theory for orbifold branes
Tetsuya Shiromizu, Shunsuke Fujii, Claudia de Rham +1
We derive an effective theory on the orbifold branes of the Randall-Sundrum 1 (RS1) braneworld scenario in the presence of a bulk brane. We concentrate on the regime where the thre…
