Supernova nucleosynthesis and neutrino oscillation

Abstract

Neutrinos play the critical roles in nucleosynthesis of light-to-heavy mass nuclei like 7Li, 11B, 138La and 180Ta in core-collapse supernovae. We find average neutrino temperatures of three flavor neutrinos so that the supernova nucleosynthesis models of the neutrino-process and the r-process can explain the observed solar-system abundance and Galactic chemical evolution of these isotopes. We propose a method to determine the unknown neutrino oscillation parameters θ 13 and mass hierarchy by the use of the MSW effects on the supernova nucleosynthesis. © 2012 American Institute of Physics.
