Primordial Nucleosynthesis: Successes and Challenges
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 کاملNeutrinos and Primordial Nucleosynthesis
The importance of the Big Bang Nucleosynthesis (BBN) as a unique tool for studying neutrino properties is discussed, and the recent steps towards a self-consistent and robust handling of the weak reaction decoupling from the thermal bath as well as of the neutrino reheating following the e − e− annihilation are summarized. We also emphasize the important role of the Cosmic Microwave Background ...
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...
