Big Bang nucleosynthesis and particle dark matter

Big Bang Nucleosynthesis and Particle Dark Matter

We review how our current understanding of the light element synthesis during the Big Bang Nucleosynthesis era may help shed light on the identity of particle dark matter.

Dark Matter and Big Bang Nucleosynthesis

The recently observed Deuterium abundance in a low-metallicity high-redshift hydrogen cloud, which is about ten times larger than that observed in the near interstellar medium, is that expected from the Standard Big Bang Nucleosynthesis theory and the observed abundances of He and Li extrapolated to their primordial values. The inferred cosmic baryon to photon ratio, η = (1.60±0.1)×10, yields a...

Big Bang Nucleosynthesis, Cosmic Microwave Background Anisotropies and Dark Energy

Over the last decade, cosmological observations have attained a level of precision which allows for very detailed comparison with theoretical predictions. We are beginning to learn the answers to some fundamental questions, using information contained in Cosmic Microwave Background Anisotropy (CMBA) data. In this talk, we briefly review some studies of the current and prospected constraints imp...
