The LBT Project V: Cosmological Implications of a New Determination of Primordial He
Tsung-Han Yeh, Keith A. Olive, Brian D. Fields +5
The primordial abundance of He plays a central role in big-bang nucleosynthesis (BBN) and in the cosmic microwave background (CMB). The LBT Project's new measuremen…
The LBT Project I: An Improved Determination of the Primordial Helium Abundance -- Project Description, Sample Selection, Observations, and Methodology
Evan D. Skillman, Richard W. Pogge, Erik Aver +9
Extremely low metallicity HII regions have been observed with the goal of determining the primordial helium abundance (). , combined with standard big bang nu…
Limits on Non-Relativistic Matter During Big-Bang Nucleosynthesis
Tsung-Han Yeh, Keith A. Olive, Brian D. Fields
Big-bang nucleosynthesis (BBN) probes the cosmic mass-energy density at temperatures MeV to keV. Here, we consider the effect of a cosmic matter-like species t…
Big-Bang Nucleosynthesis
Brian D. Fields, Paolo Molaro, Subir Sarkar
A critical review is given of the current status of cosmological nucleosynthesis. In the framework of the Standard Model with 3 types of relativistic neutrinos, the baryon-to-photo…
Big-Bang nucleosynthesis (Particle Data Group mini-review)
Brian Fields, Subir Sarkar
A critical review is given of the current status of cosmological nucleosynthesis. In the framework of the Standard Model with 3 types of relativistic neutrinos, the baryon-to-photo…
The Cosmological Parameters 2006
Ofer Lahav, Andrew R Liddle
This is a review article for The Review of Particle Physics 2006 (aka the Particle Data Book). It forms a compact review of knowledge of the cosmological parameters as at May 2006.…
Big Bang Nucleosynthesis (in "The Review of Particle Properties" 2004)
Brian Fields, Subir Sarkar
A critical review is given of the current status of cosmological nucleosynthesis. In the framework of the standard model with 3 types of relativistic neutrinos, the baryon-to-photo…
Effect of Neutrino Heating on Primordial Nucleosynthesis
B. Fields, S. Dodelson, M. S. Turner
We have modified the standard code for primordial nucleosynthesis to include the effect of the slight heating of neutrinos by annihilations. There is a small, systematic ch…
