A Brane World Solution to the Cosmological Constant Problem
arXiv:hep-th/0006068 · doi:10.1103/PhysRevLett.86.1682
Abstract
We consider a model with two parallel (positive tension) 3-branes separated by a distance in 5-dimensional spacetime. If the interbrane space is anti-deSitter, or is not precisely anti-deSitter but contains no event horizons, the effective 4-dimensional cosmological constant seen by observers on one of the branes (chosen to be the visible brane) becomes exponentially small as grows large.
