Compilation and R-matrix analysis of Big Bang nuclear reaction rates
Pierre Descouvemont, Abderrahim Adahchour, Carmen Angulo +2
We use the R-matrix theory to fit low-energy data on nuclear reactions involved in Big Bang nucleosynthesis. A special attention is paid to the rate uncertainties which are evaluat…

Updated Big-Bang Nucleosynthesis compared to WMAP results
Alain Coc, Elisabeth Vangioni-Flam, Pierre Descouvemont +2
From the observations of the anisotropies of the Cosmic Microwave Background (CMB) radiation, the WMAP satellite has provided a determination of the baryonic density of the Univers…

Updated Big Bang Nucleosynthesis confronted to WMAP observations and to the Abundance of Light Elements
A. Coc, E. Vangioni-Flam, P. Descouvemont +2
We improve Standard Big Bang Nucleosynthesis (SBBN) calculations taking into account new nuclear physics analyses (Descouvemont et al. 2003). Using a Monte-Carlo technique, we calc…
