Abstract

The last parameter of big-bang nucleosynthesis, the density of ordinary matter (baryons), is being pinned down by measurements of the deuterium abundance in high-redshift hydrogen clouds. When it is, the primeval abundances of the light elements D, ${}^{3}\mathrm{He},$ ${}^{7}\mathrm{Li},$ and ${}^{4}\mathrm{He}$ will be fixed. The first three will then become ``tracers'' in the study of Galactic and stellar chemical evolution. A precision determination of the ${}^{4}\mathrm{He}$ abundance will allow an important consistency test of big-bang nucleosynthesis and will sharpen nucleosynthesis as a probe of fundamental physics, e.g., the bound to the number of light neutrino species. An independent consistency test is on the horizon: a high-precision determination of the baryon density from measurements of the fluctuations of the cosmic background radiation temperature.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The agreement between the WMAP results and the most recent analysis of the primordial deuterium abundance yields a value of the baryon asymmetry.

    “The agreement between the WMAP results[15, 16, 17, 18] and the most recent analysis of the primordial deuterium abundance[46] yields”

    From Phase Transitions in the Early and Present Universe (2006) · cites this paper as [17]

    Section 3 (p. 5) analyzes a provisional primordial deuterium abundance and uses it to infer the baryon density, supporting the deuterium-analysis part cited as [46]. The paper does not establish that this was the most recent analysis at the time of the citing sentence; Section 6 (p. 11) treats a high-precision comparison with CBR measurements as a future test, not an agreement with WMAP results.

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.
