Brane-world cosmology of modulus stabilization with a bulk scalar field
Brane-world cosmology of modulus stabilization with a bulk scalar field
We point out that the potential of Goldberger and Wise for stabilizing the distance between two 3-branes, separated from each other along an extra dimension with a warp factor, has a metastable minimum when the branes are infinitely separated. The classical evolution of the radion (brane separation) will place it …
