Abstract:

The neutrino oscillation hypothesis does a poor job of representing the atmospheric neutrino anomaly. The anomaly is observed over 3 decades in path length and at least a factor of 30 in energy. This restricts the potential oscillation solutions to those with large amplitudes and mixing mass differences that may be ruled out by other observations. The region in the range of to leads to inconsistencies within the atmospheric neutrino data itself. The observed value of R seems to be incompatible with the most popular .

Prior experiments that were sensitive to the suggested range on fail to provide support for the Super Kamiokande conclusions.
