New constraints on the observable inflaton potential from WMAP and SDSS
Abstract
We discuss the latest constraints on a Taylor-expanded scalar inflaton potential, obtained by focusing on its observable part only, and by computing the scalar/tensor primordial spectra numerically. This is in contrast with other works in which an extrapolation of the potential is applied using the slow-roll hierarchy. We find significant differences.
