Abstract
We study F-term supergravity inflation in the framework of the Randall–Sundrum type-2 braneworld scenario. We consider a non-minimal Kähler potential and apply the slow-roll approximation in the high-energy limit to derive various perturbation spectrum parameters. We show that the η problem is solved for some coupling parameter values not allowed in standard inflation studied in Bastero-Gil et al (2007 Phys. Lett. B 651 345–51). Suitable observational values of ns are also obtained for some values of brane tension. We also calculate other spectrum inflation parameters and show that observational bounds from WMAP7, BAO and H0 data are satisfied.
