摘要: The neutrino flux close to a supernova core contributes substantially refraction so that flavor oscillations become nonlinear phenomenon. One unexpected consequence is efficient transformation for antineutrinos in region where only neutrinos encounter Mikheyev-Smirnov-Wolfenstein resonance or vice versa. Contrary previous studies we find the neutrino-driven wind electron fraction ${Y}_{e}$ always stays below 0.5, corresponding neutron-rich environment as required by r-process nucleosynthesis. relevant range of masses and mixing angles includes indicated LSND, but not atmospheric solar oscillation parameters.
