Supersymmetric hybrid inflation in the braneworld scenario

Abstract

In this paper we reconsider the supersymmetric hybrid inflation in the context of the braneworld scenario . The observational bounds are satisfied with an inflationary energy scale $\mu \simeq 4\times 10^{-4}{M}_p$, without any fine-tuning of the coupling parameter, provided that the five-dimensional Planck scale is $M_5\stackrel{<}{\sim }2\times 10^{-3}{M}_p$ . We have also obtained an upper bound on the the brane tension .
