On the Sensitivity of L/E Analysis of Super-Kamiokande Atmospheric Neutrino Data to Neutrino Oscillation Part 2 --- Four Possible L/E Analyses for the Maximum Oscillation by the Numerical Computer Experiment ---

الأصل · EN

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, Lₙu/Eₙu, Lₙu/Eₘu, Lₘu/Eₙu and Lₘu/Eₘu. Among four kinds of L/E analyses, we have shown that only Lₙu/Eₙu analysis can give the signature of maximum oscillations clearly, while the Lₘu/Eₘu analysis which are really done by Super-Kamiokande Collaboration cannot give the maximum oscillation at all. It is thus concluded that Super-Kamiokande type experiment cannot find the maximum oscillation from L/E analysis. Therefore, we would suggest Super-Kamiokande Collaboration to re-analyze the zenith angle distribution of the neutrino events which occur inside the detector carefully.
