Did something decay, evaporate, or annihilate during big bang nucleosynthesis?
Open accessAbstract
Results of a detailed examination of the cascade nucleosynthesis resulting from the putative hadronic decay, evaporation, or annihilation of a primordial relic during the big bang nucleosynthesis (BBN) era are presented. It is found that injection of energetic nucleons around cosmic time ${10}^{3}\text{ }\text{ }\mathrm{s}$ may lead to an observationally favored reduction of the primordial $^{7}\mathrm{L}\mathrm{i}/\mathrm{H}$ yield by a factor 2--3. Moreover, such sources also generically predict the production of the $^{6}\mathrm{L}\mathrm{i}$ isotope with magnitude close to the as yet unexplained high $^{6}\mathrm{L}\mathrm{i}$ abundances in low-metallicity stars. The simplest of these models operates at a fractional contribution to the baryon density ${\ensuremath{\Omega}}_{b}{h}^{2}\ensuremath{\gtrsim}0.025$, slightly larger than that inferred from standard BBN. Though further study is required, such sources, as, for example, due to the decay of the next-to-lightest supersymmetric particle into GeV gravitinos or the decay of an unstable gravitino in the TeV range of abundance ${\ensuremath{\Omega}}_{\stackrel{\texttildelow{}}{G}}{h}^{2}\ensuremath{\sim}5\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ show promise to explain both the $^{6}\mathrm{L}\mathrm{i}$ and $^{7}\mathrm{L}\mathrm{i}$ abundances in low-metallicity stars.

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.
