Collision of domain walls in asympotically Anti de Sitter spacetime

Research output: Chapter in Book/Report/Conference proceedingConference contribution


We study collision of two domain walls in 5-dimensional asymptotically Anti de Sitter spacetime. This may provide the reheating mechanism of an ekpyrotic brane universe [1], 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.
