This article suggests a new method to reconstruct the inflaton potential directly from the primordial power spectrum within canonical single-field inflation. It introduces a more generalized slow-roll approximation to reliably probe the properties of the inflaton potential. The validity of this method is discussed through several examples.
We suggest a new method to reconstruct, within canonical single-field inflation, the inflaton potential directly from the primordial power spectrum which may deviate significantly from near scale-invariance. Our approach relies on a more generalized slow-roll approximation than the standard one, and can probe the properties of the inflaton potential reliably. We give a few examples for reconstructing potential and discuss the validity of our method.
