Identifying the neutrino mass spectrum from the neutrino burst from a supernova

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 point out the distinguishing features of these schemes, and discuss the prospects of identifying the scheme from the spectra with minimal dependence on supernova models. We consider both the conventional and the inverted mass hierarchy patterns. We also estimate the earth matter effects on the spectra.
