A Quintessentially Geometric Model
arXiv:hep-ph/0603210 · doi:10.1088/1475-7516/2006/11/006
Abstract
We consider string inspired cosmology on a solitary -brane moving in the background of a ring of branes located on a circle of radius . The motion of the -brane transverse to the plane of the ring gives rise to a radion field which can be mapped to a massive non-BPS Born-Infeld type field with a cosh potential. For certain bounds of the brane tension we find an inflationary phase is possible, with the string scale relatively close to the Planck scale. The relevant perturbations and spectral indices are all well within the expected observational bounds. The evolution of the universe eventually comes to be dominated by dark energy, which we show is a late time attractor of the model. However we also find that the equation of state is time dependent, and will lead to late time Quintessence.
