| Abstract: | We consider a supersymmetric hybrid inflation in the framework of the Randall-Sundrum type-2 braneworld model. In particular, we study braneworld inflation in global supersymmetry with F-term and D-term. We
show that we can solve partially the fine-tuning problem related to scalar fields coupling constants. We also derive all known
spectrum inflationary parameters which are widely consistent with WMAP7, BAO and H
0 data, whereas the scalar spectral index n
s
>0.98 which lies outside of the range allowed by observations. |
