4D Gravity on a Brane in 5D Minkowski Space

Gia Dvali, Gregory Gabadadze, Massimo Porrati

Abstract

We suggest a mechanism by which four-dimensional Newtonian gravity emerges on a 3-brane in 5D Minkowski space with an infinite size extra dimension. The worldvolume theory gives rise to the correct 4D potential at short distances whereas at large distances the potential is that of a 5D theory. We discuss some phenomenological issues in this framework.
