Neutrino Physics and the Primordial Elemental Abundances
نویسنده
چکیده
Limits can be placed on nonstandard neutrino physics when big bang nucleosynthesis (BBN) calculations employing standard neutrino physics agree with the observationally inferred primordial abundances of deuterium (D), He, He, and Li. These constraints depend most sensitively on the abundances of D and He. New observational determinations of the primordial D and/or He abundances could force revisions in BBN constraints on nonstandard neutrino physics.

A brief review of neutrino anomalies in particle physics and of the role played by neutrinos in cosmology and astrophysics is presented. The main part of the talk is dedicated to the impact of neutrinos and in particular of neutrino oscillations on BBN and to a possible spatial variation of primordial abundances.
متن کاملThe Cosmological Energy Density of Neutrinos from Oscillation Measurements
The emerging structure of the neutrino mass matrix, when combined with the primordial element abundances, places the most stringent constraint on the flavor asymmetries in the cosmological neutrino background and therefore its energy density. I review the mechanism of synchronized neutrino oscillations in the an early universe with degenerate (asymmetric) neutrino and antineutrino densities and...
متن کامل2 Nonequilibrium massless neutrinos
The neutrino role in primordial nucleosynthesis is reviewed. The importance of nonequilibrium effects is emphasized both for the standard massless and possibly massive neutrinos. The upper bound on tau neutrino mass is presented. A spatial variation of primordial abundances and a possibility of observing them by precise measurements of the CMB anisotropy are considered.The nucleosyn-thesis boun...
متن کاملPresent status of primordial nucleosynthesis after WMAP : results from a new BBN code
We report on the status of primordial nucleosynthesis in light of recent results on CMB anisotropies from WMAP experiment. Theoretical estimates for nuclei abundances, along with the corresponding uncertainties, are evaluated using a new numerical code, where all nuclear rates usually considered have been updated using the most recent available data. Moreover, additional processes, neglected in...
متن کاملBig-Bang Nucleosynthesis in Light of Discordant Deuterium Measurements
Two dimensional concordance plots involving the baryon-to-photon ratio, η, and an effective number of light neutrinos, Nν , are used to discuss the overall consistency of standard big-bang nucleosynthesis in light of recent determinations of the primordial deuterium (H) abundance. Observations of high-redshift Ly-α clouds have provided discordant H/H determinations: one cloud with H/H high comp...
