Curved dilatonic brane worlds and the cosmological constant problem

Abstract

We construct a model for dilatonic brane worlds with constant curvature on\nthe brane, i.e. a non-zero four-dimensional cosmological constant, given in\nfunction of the dilaton coupling and the cosmological constant of the bulk. We\ncompare this family of solutions to other known dilatonic domain wall solutions\nand apply a self-tunning mechanism to check the stability of our solutions\nunder quantum fluctuations living on the brane.\n
