… The remaining (n; p) reactions we use are rates taken from Cyburt (2004). Finally we took 3
He(α;γ)7 Be from Cyburt and Davids (2008) and t(α;γ)7 Li from Cyburt (2004). We choose log-…

We reexamine the upper limits on the abundance of unstable massive relic particles provided
by the success of big-bang nucleosynthesis calculations. We use the cosmic microwave …

… These changes exacerbate the Li problem; the discrepancy is now a factor 2.4 or 4.2 σ (from
globular cluster stars) to 4.3 or 5.3 σ (from halo field stars). Possible resolutions to the …

Big bang nucleosynthesis has long provided the primary determination of the cosmic baryon
density Ω B h 2 , or equivalently the baryon-to-photon ratio, η. Recently, data on CMB …

Cosmic microwave background (CMB) determinations of the baryon-to-photon ratio η∝Ω
baryon h 2 will remove the last free parameter from (standard) big bang nucleosynthesis (BBN) …

… The new vacuum energy component is typically modelled as some scalar field ϕ. The
evolution of the scalar field is controlled by its potential as well as the Friedmann equation. …

The theoretical predictions of big bang nucleosynthesis (BBN) are dominated by uncertainties
in the input nuclear reaction cross sections. In this paper we examine the impact on BBN …

… why stars in a globular cluster—which are usually thought of as sharing a common origin
site and epoch—seem to show a larger Li dispersion and higher temperatures than field halo …

… z) crh 2/„rh 2 r2 (z/q)2…, where c is the central density, rh the core radius and q the flattening
of the halo. In the following calculations we have used q 0.8, c 0.05 M pc 3 and a value of rh …
