Keith A. Olive
TL;DR
This paper evaluates how recent observational and experimental results influence our understanding of Big Bang Nucleosynthesis, focusing on baryon density, helium abundance, and nuclear reaction rates.
Contribution
It provides an assessment of recent data and measurements, highlighting their implications for nucleosynthesis models.
Findings
Updated baryon density from Planck data affects element abundance predictions.
Recent helium abundance measurements refine primordial helium estimates.
New cross section measurement for d(p,γ)3He impacts nucleosynthesis reaction rates.
Abstract
The impact of recent results on Big Bang Nucleosynthesis is assessed. These include the Planck likelihood distributions for the baryon density; recent progress in helium abundance determinations; and a recent cross section measurement for d(p,\gamma)3He.
