Remark on approximation in the calculation of the primordial spectrum generated during inflation
arXiv:hep-ph/0007064 · doi:10.1103/PhysRevD.62.087302
Abstract
We re-examine approximations in the analytical calculation of the primordial spectrum of cosmological perturbation produced during inflation. Taking two inflation models (chaotic inflation and natural inflation) as examples, we numerically verify the accuracy of these approximations.
