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, L_mu/E_nu and L_
mu/E_mu. Among four kinds of L/E analyses, we have shown that only 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-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.
It is said that the finding of the maximum oscillation in neutrino oscillation by Super-Kamiokande is one of the major achievements of the SK. In present paper, we examine the assumption made by Super-Kamiokande Collaboration that the direction of th
e incident neutrino is approximately the same as that of the produced lepton, which is the cornerstone in their L/E analysis and we find this approximation does not hold even approximately. In the Part 2 of the subsequent paper, we apply the results from Figures 12, 13 and 14 to L/E analysis and conclude that one cannot obtain the maximum oscillation in L/E analysis which shows strongly the oscillation pattern from the neutrino oscillation.
Following the L_nu/E_nu analysis in the preceding paper of the Fully Contained Muon Events resulting from the quasi-elastic scattering obtained from our numerical computer experiment. In the present paper, we carry out the analyses of L_nu/E_mu, L_mu
/E_nu and L_mu/E_mu among four possible combinations of L and E. As the result of it, we show that we can not find the characteristis of maximum oscillation for neutrino oscillation among two of three, L_mu/E_mu and L_mu/E_nu. Only the L_nu/E_mu distribution can show something like maximum oscillation, however it cannot be detected owing to the neutral character of L_nu. It is concluded that the Super-Kamiokande Experiment could not have found the existence of the maximum oscillation for neutrino oscillation.
By referring to the procedures developed in the preceeding paper, we re-analyze the L/E distribution for Fully Contained Events resulting from quasi-elatic scattering (QEL) obtained from the Super-Kamiokande Experiment in relation to their assumption
that the direction of the incident neutrino coincide with that of the produced leptons. As the result of it, we clarify that they do not measure L_nu/E_nu distribution itself, but L_mu/E_nu distribution, which cannot show the maximum oscillation existed in the original L_nu/E_nu distribution, because L_nu could not be approximated by L_mu due to the backscattering effect and the azimuthal angle effect in QEL.
Super-Kamiokande collaboration assumes that the direction of every observed lepton coincides with the incoming direction of the incident neutrino, which is the fundamental basement throughout all their analysis on neutrino oscillation. We examine whe
ther this assumption to explain the experimental results on neutrino oscillation is theoretically acceptable. Treating every physical process concerned stochastically, we have examined if this assumption just cited is acceptable. As the result of it, we have shown that this assumption does not hold even if statistically.
In the SK analysis of the neutrino events for [Fully Contained Events] and [Partially Contained Events] on their zenith angle distribution, it is assumed that the zenith angle of the incident neutrino is the same as that of the detected charged lepto
n. In the present paper, we examine the validity of [the SK assumption on the direction] of the incident neutrinos. Concretely speaking, we analyze muon-like events due to QEL. For the purpose, we develop [Time Sequential Monte Carlo Simulation] to extract the conclusion on the validity of the SK assumption. In our [Time Sequential Simulation], we simulate every physical process concerned as exactly as possible without any approximation. From the comparison between the zenith angle distributon of the emitted muons under [the SK assumption on the direction] and the corresponding one obtained under our [Time Sequential Simulation], it is concluded that the measurement of the direction of the incident neutrino for the neutrino events occurring inside the detector in the SK analysis turns out to be unreliable, which holds irrespective of the existence and/or non-existence of the neutrino oscillation.
