Abstract
The curvaton and the inhomogeneous reheating scenarios for the generation of the cosmological curvature perturbation on large scales represent an alternative to the standard slow-roll scenario where the observed density perturbations are due to fluctuations of the inflaton field itself. The basic assumption of the curvaton and inhomogeneous reheating mechanisms is that the initial curvature perturbation due to the inflaton field is negligible. This is usually attained by lowering the energy scale of inflation thereby concluding that the amount of gravitational waves produced during inflation is highly suppressed. We show, contrary to this common lore, that the curvaton and the inhomogeneous reheating scenarios are compatible with a level of gravity-wave fluctuations which may well be observed in future satellite experiments. This conclusion does not involve, as in the slow-roll inflationary models, embarrasingly large field variations in units of the Planck scale. As a working example, we illustrate the recently proposed stringy version of old inflation.
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. No sentence in this record was written by a model.

It is important to note that the power spectrum is suppressed by $ρ^1/2=H/m$, which should be compared with the exponential suppression derived in [ref] .
