Prospects for detection of a cosmologically significant neutrino mass from a galactic supernova neutrino burst using a neutral-current-based detector

Abstract

We discuss how proposed supernova neutrino detectors could measure masses for ${\ensuremath{\nu}}_{\mathrm{\ensuremath{\mu}}}$ or ${\ensuremath{\nu}}_{\mathrm{\ensuremath{\tau}}}$ neutrinos in the range of 15 to 50 eV. The range for measurable masses might be extended down to 5 eV, depending on our confidence in some of the predicted features of the supernova-neutrino-burst signal. We discuss the expected characteristics of supernova neutrino signals in proposed neutral-current-based detectors.
