Supergravity Minimal Inflation and its Spectral Index Revisited
arXiv:hep-ph/0305286 · doi:10.1016/j.physletb.2003.09.095
Abstract
Natural supergravity models of new inflation are reconsidered as minimal inflationary models within slow-roll approximation. Their running spectral index is derived in a revised form with recent observational results and future refinements in mind. This will possibly determine essential model parameters with respect to Planck-suppressed operators.
