Abstract: (arXiv)
We investigate the muon neutrino event rate in km3^3 neutrino telescopes due to a number of galactic supernova remnants expected on the basis of these objects' known γ\gamma-ray signals. We evaluate the potential of these neutrino signals to exhibit evidence of the sub-dominant neutrino oscillations expected in various neutrino mixing schemes including pseudo-Dirac scenarios and the Exact Parity Model. With ten years' data, neutrino signals from Sgr A East should either discover or exclude neutrino oscillations governed by a δm2\delta m^2 parameter in the range 101210^{-12} to 101510^{-15} eV2^2. Such a capability is not available to terrestrial or solar system neutrino experiments.
