The neutrino mixing scheme from a supernova neutrino burst

Abstract

The current data on solar and atmospheric neutrinos admit more than one solutions in terms of the oscillations between three neutrino species. We examine the consequences of these different masses-and-mixing schemes for the observable spectra of neutrinos from the burst of a Type II supernova. We determine the characteristics of the final spectra with minimal dependence on supernova models. We point out the distinguishing features of the mixing schemes and discuss the prospects of identifying the scheme from the observed neutrino spectra.
