Abstract

We explore a version of the cosmological dilaton-fixing and decoupling mechanism in which the dilaton dependence of the low-energy effective action is extremized for infinitely large values of the bare string coupling ${g}_{s}^{2}{=e}^{\ensuremath{\varphi}}.$ We study the efficiency with which the dilaton $\ensuremath{\varphi}$ runs away toward its ``fixed point'' at infinity during a primordial inflationary stage, and thereby approximately decouples from matter. The residual dilaton couplings are found to be related to the amplitude of the density fluctuations generated during inflation. For the simplest inflationary potential $V(\ensuremath{\chi})=\frac{1}{2}{m}_{\ensuremath{\chi}}^{2}(\ensuremath{\varphi}){\ensuremath{\chi}}^{2},$ the residual dilaton couplings are shown to predict violations of the universality of gravitational acceleration near the $\ensuremath{\Delta}a/a\ensuremath{\sim}{10}^{\ensuremath{-}12}$ level. This suggests that a modest improvement in the precision of equivalence principle tests might be able to detect the effect of such a runaway dilaton. Under some assumptions about the coupling of the dilaton to dark matter and/or dark energy, the expected time variation of natural ``constants'' (in particular of the fine-structure constant) might also be large enough to be within reach of improved experimental or observational data.

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.
