Neutrino Mass Hierarchy and Stepwise Spectral Swapping of Supernova Neutrino Flavors

Huaiyu Duan, George M. Fuller, J. Carlson +1

We examine a phenomenon recently predicted by numerical simulations of supernova neutrino flavor evolution: the swapping of supernova ${\nu }_e$ and ${\nu }_{\mu ,\tau }$ energy spectra below (abov…
