Particle-Theory And Field-Theory Models Of The Early Universe, Strings And Branes
Scientific paper
We construct the solutions correspond to intersections of 4-branes on a 3-brane in AdS6 with Minkowski, de Sitter and Anti-de Sitter geometries intrinsic to the 3-brane. The Minkowski and de Sitter solutions localize gravity to the intersection, leading to 4D Newtonian gravity at large distances. The effective 4D Planck scale depends on the square of the fundamental 6D Planck scale, the AdS6 radius and the angles between the 4-branes and the radial AdS direction. We comment on the early universe cosmology of such models. Finally we describe how to generalize these solutions to the case of AdS4+n, n > 2, where n n + 2-branes intersect on a 3-brane.
