Primordial Nucleosynthesis For The New Millennium
The physics of the standard hot big bang cosmology ensures that the early Universe was a primordial nuclear reactor, synthesizing the light nuclides (D, 3 He, 4 He, and 7 Li) in the first 20 minutes of its evolution. After an overview of nucleosynthesis in the standard model (SBBN), the primordial abundance yields will be presented, followed by a status report (intended to stimulate further dis...
متن کاملNew results in primordial nucleosynthesis
Big Bang Nucleosynthesis (BBN) is one of the most powerful tools to study fundamental interactions since light nuclei abundances crucially depend on many elementary particle properties, like the number of effective neutrino degrees of freedom, Nν . At the moment, however, recent data on Hemass fraction, Y4, and Deuterium (D) and Li abundances, Y2 ≡ D/H and Y7 ≡ 7 Li/H , produced during BBN are ...
متن کاملPrimordial Nucleosynthesis
Primordial nucleosynthesis provides a probe of the Universe during its early evolution. Given the progress exploring the constituents, structure, and recent evolution of the Universe, it is timely to review the status of Big Bang Nucleosynthesis (BBN) and to confront its predictions, and the constraints which emerge from them, with those derived from independent observations of the Universe at ...
متن کاملPrimordial Nucleosynthesis : Accurate Predictions
Big Bang Nucleosynthesis (BBN) represents a key subject of modern cosmology since it is a powerful tool to study fundamental interactions. In the recent years, the improvement on the measurement accuracy of light primordial nu-clei abundances allowed BBN to enter in a sort of precision era. In view of this, a great theoretical effort has been devoted to make theoretical predictions comparably a...
متن کاملPrimordial Nucleosynthesis After WMAP
During its early evolution, the hot, dense Universe provided a laboratory for probing fundamental physics at high energies. By studying the relics from those early epochs, such as the light elements synthesized during primordial nucleosynthesis when the Universe was only a few minutes old, and the relic, cosmic microwave photons, last scattered when the protons, alphas, and electrons (re)combin...
