Second Order General Slow-roll Power Spectrum
نویسنده
چکیده
Recent combined results from theWilkinson Microwave Anisotropy Probe (WMAP) and Sloan Digital Sky Survey (SDSS) provide a remarkable set of data which requires more accurate and general investigation. Here we derive formulae for the power spectrum P(k) of the density perturbations produced during inflation in the general slowroll approximation with second order corrections. Also, using the result, we derive the power spectrum in the standard slow-roll picture with previously unknown third order corrections. KAIST-TH/2004-05 ∗[email protected]

From the Spectrum to Inflation: A Second Order Inverse Formula for the General Slow-Roll Spectrum
We invert the second order, single field, general slow-roll formula for the power spectrum, to obtain a second order formula for inflationary parameters in terms of the primordial power spectrum. ∗[email protected]
متن کاملThe spectrum of cosmological perturbations produced by a multi-component inflaton to second order in the slow-roll approximation
We derive general analytic formulae for the power spectrum and spectral index of the curvature perturbation produced during inflation driven by a multi-component inflaton field, up to the second order in the slow-roll approximation. We do not assume any specific properties of the potential or the metric on the scalar field space, except for the slow-roll condition, Einstein gravity, and the abs...
متن کاملSlow-Roll Spectrum for Gravitational Waves
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. KAIST-TH/2004-10 [email protected]
