Signal for supernova ${\nu }_{\mu }$ and ${\nu }_{\tau }$ neutrinos in water Čerenkov detectors

K. Langanke, P. Vogel, E. Kolbe

We suggest that photons with energies between 5 and 10 MeV, generated by the ($\nu ,{\nu }^{\prime }p\gamma$) and ($\nu ,{\nu }^{\prime }n\gamma$) reactions on ${}^{16}$O, constitute a signal which allows a unique identificati…
