Supernova Neutrinos

Abstract

I describe how the signals corresponding to the supernova $\nu_e$ and $\bar{\nu}_e$ (charged current reactions) as well as all active neutrinos (neutral current reactions) can be separately observed in various existing detectors. These observations would make it possible to determine the flux and average energy (or temperature) for each of these three neutrino signal components. I argue that all these quantities are needed in order to understand the interplay between the so far poorly known supernova neutrino emission process and the neutrino oscillations.
