Assisted Inflation in Randall-Sundrum Scenario
arXiv:hep-ph/0109076 · doi:10.1016/S0370-2693(02)01226-1
Abstract
We extend the Randall-Sundrum(RS) model by adding a fundamental scalar field in the bulk, then study the multi-field assisted inflationary solution on brane. We will show that this model satisfies not only the observation, but also provides a solution to hierarchy problem. Furthermore in comparison with the chaotic inflation model with a single field in four space-time dimension, the parameters in our model required for a successful inflation are natural.
