Abstract

The flavor transition mechanisms of supernova neutrinos as they propagate outward from the deep inside of a supernova are yet to be determined. We study the time-evolution patterns of different neutrino flavors in various flavor transition scenarios. With simulation data of supernova neutrinos, we calculate the neutrino event rates at different kinds of detectors for different flavor transition scenarios. Using the calculated event rates of IBD and ν_eAr in corresponding liquid scintillation detectors and liquid argon detectors, we calculate the ratios of two cumulative time distribution up to t = 100 ms in Nakazato's supernova models with 13, 20, and 30 M☉ progenitor mass. We show that the time evolutions of cumulative ratios are effective in determining whether MSW oscillations really occur.
