The determination of the primeval deuterium abundance has opened a precision era in big bang nucleosynthesis, making accurate predictions more important than ever before. We present in analytic form new, more precise predictions for the light-element abundances and their error matrix. Using our predictions and the primeval deuterium abundance, we infer a baryon density of ΩBh2 = 0.020 ± 0.002 (95% confidence level) and find no evidence for stellar production (or destruction) of 3He beyond… 

Big-Bang Nucleosynthesis after Planck

We assess the status of big-bang nucleosynthesis (BBN) in light of the final Planck data release and other recent developments, and in anticipation of future measurements. Planck data from the

Big bang nucleosynthesis

Abstract We present an overview of the standard model of big bang nucleosynthesis (BBN), which describes the production of the light elements in the early universe. The theoretical prediction for the


We present recent determinations of the cosmological baryon density ρ b, extracted from different kinds of observational data. The baryon density range is not very wide and is usually interpreted as

Updated Big Bang nucleosynthesis confronted to WMAP observations and to the abundance of light elements

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 calculate the

Constraining the helium abundance with CMB

We consider for the first time the ability of present-day cosmic microwave background (CMB) anisotropies data to determine the primordial helium mass fraction, Y_p. We find that CMB data alone gives

The cosmological density of baryons from observations of 3He+ in the Milky Way

The earlier observations, when combined with recent theoretical developments in the understanding of light-element synthesis and destruction in stars, allow us to determine an upper limit for the primordial abundance of 3He relative to hydrogen: 3He/H = (1.1 ± 0.2) × 10-5.



What is the big-bang-nucleosynthesis prediction for the baryon density and how reliable is it?

Together, the standard theory of big-bang nucleosynthesis (BBN) and the primeval deuterium abundance now very precisely peg the baryon density. Based upon our analysis of the deuterium data and the

Quantifying uncertainties in primordial nucleosynthesis without Monte Carlo simulations

We present a simple method for determining the (correlated) uncertainties of the light element abundances expected from big bang nucleosynthesis, which avoids the need for lengthy Monte Carlo

Experimental, computational, and observational analysis of primordial nucleosynthesis

We present a comprehensive evaluation of the current status of the standard theory of primordial nucleosynthesis. We determine the 12 nuclear reactions most important for the production of the light

Estimating reaction rates and uncertainties for primordial nucleosynthesis

We present a Monte Carlo method for direct incorporation of nuclear inputs in primordial nucleosynthesis calculations. This method is intended to remedy shortcomings of current error estimation, by

Primordial Lithium and Big Bang Nucleosynthesis

It is shown that the observed Li versus Fe trend provides a strong discriminant between alternative models for Galactic chemical evolution of the light elements at early epochs and is limited as much by uncertainties in the nuclear cross sections used in big bang nucleosynthesis (BBN) calculations as by the observed abundance itself.

Review of Big Bang Nucleosynthesis and Primordial Abundances

Big Bang Nucleosynthesis (BBN) is the synthesis of the light nuclei, Deuterium (D or 2H), 3He, 4He and 7Li during the first few minutes of the universe. This review concentrates on recent

Big-bang nucleosynthesis enters the precision era

The last parameter of big-bang nucleosynthesis, the baryon density, is being pinned down by measurements of the deuterium abundance in high-redshift hydrogen clouds. When it is determined, it will

An Accurate Calculation of the Big Bang Prediction for the Abundance of Primordial Helium

Within the standard models of particle physics and cosmology we have calculated the big-bang prediction for the primordial abundance of {sup 4}He to a theoretical uncertainty of less than
