Description
We present a method to verify Mikheyev-Smirnov-Wolfenstein effect during the propagation of SN neutrinos from the SN core to the Earth. The non-MSW scenario to be distinguished from the MSW one is the
incoherent flavor transition probability for neutrino propagation in the vacuum. Our approach involves studying time evolution of neutrino event rates in liquid Argon, liquid scintillation and water Cherenkov detectors. Using currently available simulations for SN neutrino emissions, the time evolution of $\nu_e{\rm Ar}$ event rates and $\bar{\nu}_e$ inverse beta-decay event rates and the corresponding cumulative event fractions are calculated up to t=100
ms in DUNE, JUNO and Hyper-Kamiokande detectors, respectively. It is shown that the area under the cumulative time distribution curve from t=0 to t=100 ms in each detector and their ratio can be used to discriminate different flavor transition scenarios of SN neutrinos.
