Toward Solving the Cosmological Constant Problem?
arXiv:hep-th/0212101 · doi:10.1142/S0217751X0301509X
Abstract
We discuss the cosmological constant problem in the context of higher codimension brane world scenarios with infinite-volume extra dimensions. In particular, by adding higher curvature terms in the bulk action we are able to find smooth solutions with the property that the 4-dimensional part of the brane world-volume is flat for a range of positive values of the brane tension.
