Abstract
A new analysis method for supernova model identification using supernova neutrino observations in Super-Kamiokande (SK) is developed. This new method uses information on late-phase neutrinos observed in SK, such as the duration of supernova neutrino and average neutrino energy. In this paper, we report the evaluation results of the supernova identification performance, demonstrating 90% or more in identification performance.
