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…

The Neutron Mean Life and Big Bang Nucleosynthesis
Tsung-Han Yeh, Keith A. Olive, Brian D. Fields
We explore the effect of neutron lifetime and its uncertainty on standard big-bang nucleosynthesis (BBN). BBN describes the cosmic production of the light nuclides , ${\…

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…
