Study on Supernova Neutrinos

Next-generation large detectors of $10-100 kton scale are expected to gather thousands to ten thousands of events from a nearby supernova (SN) explosion. With such amount of events, the SN neutrino spectrum, the light curve, and the mean energy can be measured with much higher precisions. As 99 energy of SN explosions is carried away by neutrinos, analyzing these events should greatly increase our understanding of SN physics and neutrino properties. By studying SN neutrino interactions in large scintillation detectors, we explore the effect of neutrino properties, such as neutrino mass hierarchy (NMH), on the compositions of flavor, energy and time structure of SN neutrinos. On the other hand, the measured neutrino spectra and light curves of different flavors will be used to probe the model of SN explosion.
