| ABSTRACT: |
In this talk, I will show how to naturally reduce the spectral index of supernatural inflation to fit recent WMAP data by making it into a hilltop inflation. I will also show the regime within which there is no gravitino problem even if we consider both thermal and nonthermal production mechanisms. |
