On the Relation between the True Directions of Neutrinos and the Reconstructed Directions of Neutrinos in L/E Analysis Performed by Super-Kamiokande Collaboration Part1

TL;DR

This paper critically examines the assumption used in Super-Kamiokande's neutrino oscillation analysis, demonstrating through numerical experiments that the neutrino and lepton directions do not align, which questions the validity of their L/E oscillation results.

Contribution

The study provides a numerical analysis showing the discrepancy between neutrino and lepton directions, challenging a key assumption in Super-Kamiokande's L/E analysis.

Findings

The neutrino and lepton directions do not approximately match.

The assumption used in Super-Kamiokande's analysis is invalid.

Maximum oscillation cannot be confirmed in their L/E analysis due to this discrepancy.

Abstract

It should be regarded that the confirmation of the maximum oscillation in neutrino oscillation through L/E analysis by Super-Kamiokande is a logical consequence of their establishment on the existence of neutrino oscillation through the analysis of the zenith angle distribution for atmospheric neutrino events. In the present paper (Part1) with the computer numerical experiment, we examine the assumption made by Super-Kamiokande Collaboration that the direction of the 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 a subsequent paper (Part2), we apply the results from Figures 16, 17, 18 and 19 to L/E analysis and conclude that one cannot obtain the maximum oscillation in L/E analysis in the single ring muon events due to quasi-elastic scattering reported by Super-Kamiokande which shows strongly the oscillation pattern from the neutrino oscillation.
