Query: TeV Neutrinos and GeV Photons from Shock Breakout in Supernovae   We show that as a Type II supernova shock breaks out of its progenitor star,
it becomes collisionless and may accelerate protons to energies >10 TeV.
Inelastic nuclear collisions of these protons produce a ~1 hr long flash of TeV
neutrinos and 10 GeV photons, about 10 hr after the thermal (10 MeV) neutrino
burst from the cooling neutron star. A Galactic supernova in a red supergiant
star would produce a photon and neutrino flux of ~10^{-4} erg/cm^2 s. A km^2
neutrino detector will detect ~100 muons, thus allowing to constrain both
supernova models and neutrino properties.
