Phys. Rev. Lett. 87, 071101 (2001) [4 pages]TeV Neutrinos and GeV Photons from Shock Breakout in SupernovaeReceived 20 February 2001; published 30 July 2001 We show that as a Type II supernova shock breaks out of its progenitor star, it becomes collisionless and may accelerate protons to energies >10TeV. Inelastic nuclear collisions of these protons produce an ∼1h long flash of TeV neutrinos and 10 GeV photons, about 10h 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 ∼10-4ergcm-2s-1. A km2 neutrino detector will detect ∼100muons, thus allowing to constrain both supernova models and neutrino properties. © 2001 The American Physical Society URL:
