Research output: Contribution to journalArticlepeer-review

29 Scopus citations


We derive the power spectrum Pψ (k) of the gravitational waves produced during general classes of inflation with second-order corrections. Using this result, we also derive the spectrum and the spectral index in the standard slow-roll approximation with new higher order corrections.
