The numerical computer experiment for the neutrino events with the SK neutrino oscillation parameters occurring outside the Superkamiokande detector

TL;DR

This study uses a computer simulation to analyze neutrino events outside the Super-Kamiokande detector, comparing results with real data to evaluate neutrino oscillation parameters, but finds it challenging to confirm oscillation claims.

Contribution

It introduces a numerical experiment simulating neutrino events outside the detector to compare with actual data, providing a new approach to test oscillation parameters.

Findings

Simulation results align with real data but do not conclusively confirm neutrino oscillation.

Difficulty in validating SK's neutrino oscillation parameters through external event analysis.

Highlights limitations of current methods in confirming neutrino oscillation phenomena.

Abstract

Adopting neutrino oscillation parameters obtained by Super-Kamiokande, a numerical computer experiment for neutrino events occurring outside the detector, is carried out in the same SK live days, 1645.9 live days, constructing the virtual Super-Kamiokande detector in the computer. The numerical results by the computer experiment could be directly compared with the real SK experimental data. The comparison shows that it is difficult to obtain convincing conclusion on the existence of the neutrino oscillation with specified neutrino oscillation parameters claimed by SK through analysis for neutrino events occurring outside the detector.
