Probing Physics Beyond the Standard Model: Limits from BBN and the CMB Independently and Combined
Tsung-Han Yeh, Jessie Shelton, Keith A. Olive +1
We present new Big Bang Nucleosynthesis (BBN) limits on the cosmic expansion rate or relativistic energy density, quantified via the number of equivalent neutrino species. We…
Axion Kinetic Misalignment and Parametric Resonance from Inflation
Raymond T. Co, Lawrence J. Hall, Keisuke Harigaya +2
Axion cold dark matter from standard misalignment typically requires a decay constant GeV. Kinetic misalignment and parametric resonance easily allow lower va…
An MCMC determination of the primordial helium abundance
Erik Aver, Keith A. Olive, Evan D. Skillman
Spectroscopic observations of the chemical abundances in metal-poor H II regions provide an independent method for estimating the primordial helium abundance. H II regions are desc…
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…
