Collision of Domain Walls in asymptotically Anti de Sitter spacetime
arXiv:hep-th/0603076 · doi:10.1103/PhysRevD.73.103508
Abstract
We study collision of two domain walls in 5-dimensional asymptotically Anti de Sitter spacetime. This may provide the reheating mechanism of an ekpyrotic (or cyclic) brane universe, in which two BPS branes collide and evolve into a hot big bang universe. We evaluate a change of scalar field making the domain wall and can investigate the effect of a negative cosmological term in the bulk to the collision process and the evolution of our universe.
