Primordial Nucleosynthesis, Cosmic Microwave Background and Neutrinos
G. Mangano, A. Melchiorri, O. Pisanti
Abstract
We report the results of a recent likelihood analysis combining the primordial nucleosynthesis and the BOOMERanG and MAXIMA-1 data on cosmic microwave background radiation anisotropies. We discuss the possible implications for relic neutrino background of a high value for the baryonic matter content of the universe, larger than what is expected in a standard nucleosynthesis scenario.
