Solar Neutrino Constraints on the BBN Production of Li
Richard H. Cyburt, Brian D. Fields, Keith A. Olive
Using the recent WMAP determination of the baryon-to-photon ratio, 10^{10} η= 6.14 to within a few percent, big bang nucleosynthesis (BBN) calculations can make relatively accurate…
A Re-examination of the Re Bound on the Variation of Fundamental Couplings
Keith A. Olive, Maxim Pospelov, Yong-Zhong Qian +4
We reconsider the Re187 bound on the variation of the fine-structure constant. We combine the meteoritic measurement with several present-day lab measurements to firmly establish t…
The Chemical Evolution of Mg Isotopes vs. the Time Variation of the Fine Structure Constant
T. Ashenfelter, Grant J. Mathews, Keith A. Olive
The many-multiplet method applied to high redshift quasar absorption spectra has indicated a possible time variation of the fine structure constant. Alternatively, a constant value…
Primordial Nucleosynthesis in Light of WMAP
Richard H. Cyburt, Brian D. Fields, Keith A. Olive
Big bang nucleosynthesis has long provided the primary determination of the cosmic baryon density $\omb h^2$, or equivalently the baryon-to-photon ratio, η. Recently, data on CMB a…
TASI Lectures on Dark Matter
Keith A. Olive
Observational evidence and theoretical motivation for dark matter are presented and connections to the CMB and BBN are made. Problems for baryonic and neutrino dark matter are summ…
