- Abstract
Big Bang Nucleosynthesis (BBN) explores the first few minutes of nuclei formation during the Big Bang. We present updated 2 for the abundances of the four primary light nuclides - D, 3He, 4He, and 7Li - in BBN. A modified standard BBN code was used in a Monte Carlo analysis of the nucleosynthesis uncertainties as a function of the baryon-to-photon ratio. Reaction rates were updated to those of NACRE, REACLIB, and -Matrix calculations. The results were then used to derive a new constraint on the effective number of neutrinos.
