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 ---

摘要

In the previous paper (Part~1), we have verified that the SK assumption onthe direction does not hold in the analysis of neutrino events occurred insidethe SK detector. We have made four possible L/E analyses, L_nu/E_nu, L_nu/E_mu,L_mu/E_nu and L_mu/E_mu. Among four kinds of L/E analyses, we have shown thatonly L_nu/E_nu analysis can give the signature of maximum oscillations clearly,while the L_mu/E_mu analysis which are really done by Super-KamiokandeCollaboration cannot give the maximum oscillation at all. It is thus concludedthat Super-Kamiokande type experiment cannot find the maximum oscillation fromL/E analysis. Therefore, we would suggest Super-Kamiokande Collaboration tore-analyze the zenith angle distribution of the neutrino events which occurinside the detector carefully.
