Gravity on a Dilatonic Gauss-Bonnet Brane World
arXiv:hep-th/0408139
Abstract
The effective four-dimensional, linearised gravity of a Randall-Sundrum-like brane world model is analysed. The model includes higher order curvature terms (such as the Gauss-Bonnet term) and a scalar field. The resulting brane worlds can have better agreement with observations than the equivalent Einstein gravity models.
