Can Super-Lamiokande atmospheric neutrino data be explained by flavor-changing induced neutrino oscillations?

Abstract

We reexamine the possibility of explaining the latest Super-Kamiokande atmospheric neutrino data including the upward going muon data by means of flavor-changing induced massless neutrino oscillations. We show that the energy independence of such flavor-changing coversion clearly leads to incompatibility between the upward going passing muons and the other samples, unless the flux of passing muons is larger than expected.
