It is shown that the results of the Super-Kamiokande atmospheric neutrino experiment, interpreted in terms of nu_mu<--->nu_tau flavor transitions, can probe possible decoherence effects induced by new physics (e.g., by quantum gravity) with…

We suggest that the atmospheric neutrino anomaly observed in the Super-Kamiokande (and other) experiments results from the combined effects of muon-neutrino to tau-neutrino oscillations with a Delta m^2 value of approximately 0.4 eV^2 and…

If the correct interpretation of the Super-Kamiokande atmospheric neutrino data is \nu_\mu -> \nu_\tau oscillation, the contained data sample should already have more than 10 tau appearance events. We study the challenging task of detecting…

The evidence for $\nu_\mu$ disappearance in the Super-Kamiokande atmospheric neutrino experiment and the negative searches for $\nu_e$ disappearance in the CHOOZ reactor experiment can be easily reconciled by assuming oscillations with…

In the previous paper (Part~1), we have verified that the SK assumption on the direction does not hold in the analysis of neutrino events occurred inside the SK detector. We have made four possible L/E analyses, L_nu/E_nu, L_nu/E_mu,…

The atmospheric muon neutrino deficit, which was possible evidence of $\nu_\mu \leftrightarrow \nu_\tau$ oscillation, was reported by the Kamiokande experiment from 1988. Many experimental efforts were made to examine the Kamiokande…

Observations of atmospheric neutrinos offer compelling evidence that neutrinos have mass and do oscillate. Preliminary data are compatible with maximal $\nu_\mu$--$\nu_\tau$ mixing, but not with pure $\nu_\mu$--$\nu_e$ mixing. In a general…
