What Would We Learn by Detecting a Gravitational Wave Signal in the Cosmic Microwave Background Anisotropy?

Open access

Abstract

Inflation generates gravitational waves, which may be observable in the low multipoles of the cosmic microwave background anisotropy but only if the inflaton field variation is at least of order the Planck scale. Such a large variation would imply that the model of inflation cannot be part of an ordinary extension of the standard model, and combined with the detection of the waves it would also suggest that the inflaton field cannot be one of the superstring moduli. Another implication of observable gravitational waves would be a potential ${V}^{1/4}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2$ to $4\ifmmode\times\else\texttimes\fi{}{10}^{16}\phantom{\rule{0ex}{0ex}}\mathrm{GeV}$, which is orders of magnitude bigger than the prediction of most models.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
