AdS braneworld with Backreaction
We review the tachyon model derived from the dynamics of a 3-brane moving in
the AdS5 bulk. The bulk geometry is based on the Randall-Sundrum II model
extended to include the radion. The effective tachyon Lagrangian is modified
due to the back-reaction of the brane on the bulk geometry.Comment: 21 pages, 5 figures, typos corrected, a refference added, based on
