# Influence of the variation of fundamental constants on the primordial nucleosynthesis

@article{Coc2013InfluenceOT, title={Influence of the variation of fundamental constants on the primordial nucleosynthesis}, author={Alain Coc and Pierre Descouvemont and Jean-Philippe Uzan and Elisabeth Vangioni}, journal={arXiv: Cosmology and Nongalactic Astrophysics}, year={2013} }

We investigate the effect of a variation of fundamental constants on primordial element production in Big Bang nucleosynthesis (BBN). We focus on the effect of a possible change in the nucleon-nucleon interaction on nuclear reaction rates involving the A=5 (5Li and 5He) and A=8 (8Be) unstable nuclei. The reaction rates for 3He(d,p)4He and 3H(d,n)4He are dominated by the properties of broad analog resonances in 5Li and 5He compound nuclei respectively. While the triple-alpha process 4He(aa,g)12C…
