TL;DR
This paper discusses modifications to supernatural inflation to achieve a spectral index of 0.96 and examines constraints on reheating temperature from gravitino production related to Big Bang Nucleosynthesis.
Contribution
It presents a method to adjust supernatural inflation for a specific spectral index and analyzes reheating temperature constraints from gravitino production.
Findings
Spectral index can be tuned to n_s=0.96 in supernatural inflation.
Reheating temperature constraints are derived from gravitino production considerations.
Both thermal and non-thermal gravitino production are analyzed.
Abstract
In this talk, I will explain how to reduce the spectral index to be n_s=0.96 for supernatural inflation. I will also show the constraint to the reheating temperature from Big Bang Nucleosynthesis of both thermal and non-thermal gravitino production.
