Inflationary attractor in Gauss Bonnet brane cosmology
/ Authors
/ Abstract
The inflationary attractor properties of the canonical scalar field and Born?Infeld field are investigated in the Randall?Sundrum II scenario with a Gauss?Bonnet term in the bulk action. We find that the inflationary attractor property will always hold for both the canonical and Born?Infeld fields for any allowed non-negative Gauss?Bonnet coupling. We also briefly discuss the possibility of explaining the suppressed lower multiples and running a scalar spectral index simultaneously in the scenario of Gauss?Bonnet brane inflation.
