Hierarchy problem and the cosmological constant in a five-dimensional Brans-Dicke brane world model
arXiv:1010.6079 · doi:10.1007/s10714-010-1026-0
Abstract
We discuss a new solution, admitting the existence of dS_{4} branes, in five-dimensional Brans-Dicke theory. It is shown that, due to a special form of a bulk scalar field potential, for certain values of the model parameters the effective cosmological constant can be made small on the brane, where the hierarchy problem of gravitational interaction is solved. We also discuss new stabilization mechanism which is based on the use of auxiliary fields.
