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 H0 data, whereas the scalar spectral index ns>0.98 which lies outside of the range allowed by observations.
