Experimental, computational, and observational analysis of primordial nucleosynthesis
Abstract
We present a comprehensive evaluation of the current status of the standard theory of primordial nucleosynthesis, determining the 12 nuclear reactions most important for the production of the light elements and conducting a detailed study of their rates and uncertainties; these are incorporated into a Monte Carlo analysis to evaluate uncertainties in the computed elemental abundances. These predicted abundances are compared with primordial abundances deduced from astronomical observations of the light elements D, He-3, He-4, and Li-7; consistent agreement exists over a narrow range of the baryon-to-photon ratio n, thereby supporting the standard theory of big bang nucleosynthesis. This n range corresponds to a constraint on the baryon density parameter of 0.01-0.09, where the primordial D + He-3 abundance sets the lower bound and the He-4 abundance sets the upper bound. The new reaction rates cause an increase in the upper bound from Li-7 by 40 percent over that determined in previous studies.

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.
