Query: Reconstruction of supernova {\nu}_{\mu}, {\nu}_{\tau}, anti-{\nu}_{\mu},
  and anti-{\nu}_{\tau} neutrino spectra at scintillator detectors   We present a new technique to directly reconstruct the spectra of mu/tau
neutrinos and antineutrinos from a supernova, using neutrino-proton elastic
scattering events (nu+p to nu+p) at scintillator detectors. These neutrinos,
unlike electron neutrinos and antineutrinos, have only neutral current
interactions, which makes it very challenging, with any reaction, to detect
them and measure their energies. With updated inputs from theory and
experiments, we show that this channel provides a robust and sensitive measure
of their spectra. Given the low yields and lack of spectral information in
other neutral current channels, this is perhaps the only realistic way to
extract such information. This will be indispensable for understanding flavor
oscillations of SN neutrinos, as it is likely to be impossible to disentangle
neutrino mixing from astrophysical uncertainties in a SN without adequate
spectral coverage of all flavors. We emphasize that scintillator detectors,
e.g., Borexino, KamLAND, and SNO+, have the capability to observe these events,
but they must be adequately prepared with a trigger for a burst of low-energy
events. We also highlight the capabilities of a larger detector like LENA.
