Abstract

The recently released Planck data have constrained 4-dimensional inflationary parameters even more accurately than ever. We consider an extension of the braneworld model with induced gravity and a non-minimally coupled scalar field on the brane. We constraint the inflation parameters in this setup, by adopting six types of potential, in confrontation with the joint Planck+WMAP9+BAO data. We show that a potential of the type V(φ)=V₀exp(-βφ) has the best fit with newly released observational data.
