| Research Abstract |
We investigate flavor conversions and future observations of supernova neutrinos assuming Majorana neutrinos with finite transition magnetic moments. In the case of inverted mass hierarchy and large mixing angle θ13, the effects of the neutrino magnetic moment will be observed in the time variation of the neutrino energy spectra in Super-Kamiokande and the total neutrino events in future liquid Ar detectors. We also investigate light element synthesis in Type Ic supernovae and the effects of neutrino oscillations in r-process nucleosynthesis.
