Sterile neutrinos and supernova nucleosynthesis
D. O. Caldwell, G. M. Fuller, Y. -Z. Qian
A light sterile neutrino species has been introduced to explain simultaneously the solar and atmospheric neutrino puzzles and the results of the LSND experiment, while providing fo…
Transformation-Induced Nonthermal Neutrino Spectra and Primordial Nucleosynthesis
Kevork Abazajian, Xiangdong Shi, George M. Fuller
We examine in detail the changes in the production of primordial helium resulting from nonthermal neutrino momentum distributions produced by resonant transformation of electron-ty…
Comments Regarding "On Neutrino-Mixing-Generated Lepton Asymmetry and the Primordial Helium-4 Abundance"
Xiangdong Shi, George M. Fuller, Kevork Abazajian
This is a reply to the preprint "On Neutrino-Mixing-Generated Lepton Asymmetry and the Primordial Helium-4 Abundance" by M. V. Chizhov and D. P. Kirilova (hep-ph/9908525), which cr…
The Increase in the Primordial He-4 Yield in the Two-Doublet Four-Neutrino Mixing Scheme
Kevork Abazajian, George M. Fuller, Xiangdong Shi
We assess the effects on Big Bang Nucleosynthesis (BBN) of lepton number generation in the early universe resulting from the two-doublet four-neutrino mass/mixing scheme. It has be…
Neutrino-Mixing-Generated Lepton Asymmetry and the Primordial He Abundance
Xiangdong Shi, George M. Fuller, Kevork Abazajian
It has been proposed that an asymmetry in the electron neutrino sector may be generated by resonant active-sterile neutrino transformations during Big Bang Nucleosynthesis (BBN). W…
Active-Sterile Neutrino Mixing in the Early Universe and Primordial Nucleosynthesis
Kevork Abazajian, Xiangdong Shi, George M. Fuller
We investigate the effects of matter-enhanced (MSW) transformation of neutrinos in the Early Universe on the primordial helium yield (Y_p). We find that Y_p is affected much more b…
