The uncertainty in the calculation of atmospheric neutrino fluxes is studied. The absolute value of atmospheric neutrino fluxes is sensitive to variation of the primary cosmic ray flux model and/or the interaction model. However, the ratios between different kind of neutrinos stay almost unchanged with these variations. It is unlikely that the anomalous ratio (νµ/νe) obs /(νµ/νe)MC reported by ...

N ov 1 99 8 Neutrino Oscillations : a source of Goldstone fields and consequences for Supernovae ∗

It is shown that true Nambu-Goldstone (NG) bosons develop coherent fields whenever the associated charges of the matter particles are not conserved in a macroscopic scale. The sources of the NG fields are the time rates of quantum number violation. If the lepton numbers are spontaneously broken at a scale below 1 TeV, the neutrino oscillation processes generate classic NG fields that are strong...

The gauge-mediated supersymmetry breaking mechanism is one of the most reliable scenario which naturally suppresses the large flavor changing neutral current and CP violation in the supersymmetric standard model. When the messenger fields have suitable B − L charges, the radiative correction naturally induces the Zee-like neutrino mass matrix, which provides tiny neutrino masses and large lepto...
