Curved dilatonic brane-worlds and the cosmological constant problem
Natxo Alonso-Alberca, Bert Janssen, Pedro J. Silva
Abstract
We construct a model for dilatonic brane worlds with constant curvature on the brane, i.e. a non-zero four-dimensional cosmological constant, given in function of the dilaton coupling and the cosmological constant of the bulk. We compare this family of solutions to other known dilatonic domain wall solutions and apply a self-tunning mechanism to check the stability of our solutions under quantum fluctuations living on the brane.
